Chapter 638

Lu Li sat in front of the test bench.

On the left side of the test bench, there is a small box containing the spores of the giant algae.

Although mature algae are at least tens of meters long, most of them are more than 100 meters long. However, the spores of the giant algae are very small, about the size of a needle tip.

That's normal. Human eggs are only that big.

Lu Li took out a thin tube suction needle from the toolbox of the test-bed and sucked out some sporophytes from the spore box.

When taking out the sporophyte, Lu Li's right hand shakes a lot, and several spores fall on Lu Li's left hand.

Fingertip touch, pinch the spores, Lu Li's consciousness with the move, fingertip touch into the spores.

In order to maintain the glorious image of "teacher can do anything", this experiment must be successful. All Is it understandable to do something wrong with the extraordinary power of heaven and man?

One mind and two uses.

While Lu Li infiltrated the spores with the spirit consciousness, he moved the thin tube suction needle and put the spores into the electron microscope slide on the test bench.

"Before we do gene editing, we must first clearly understand the genetic information of the giant algae."

Lu Li said, reaching out to open the electron microscope. The screen lights up, showing the internal structure of the spores.

In fact, part of Lu Li's spirit consciousness has penetrated into the giant algal spores in his hand. He can observe them closely and feel everything inside the spores himself.

With Lu Li's level of knowledge and personal experience in the interior of spores, the structure, composition and operation mechanism of spores were soon understood.

Lu Li pointed to the image of spore structure on the display screen of the electron microscope to explain to the students the internal structure of spores, the components and functions of each part.

"This is the mitochondria inside the spore cell. They are the generators of cells, and the mechanism is like this... "

"This is the chain protein inside the spore cell. They connect with each other to form a highway inside the cell."

"This is the motor protein inside the spore cell. They are molecular level porters, or drivers inside the cell, shuttling back and forth on the chain protein highway to deliver energy to the cell."

Following his own consciousness, Lu Li went deep into the spore cells and observed the situation. On the display screen of the electron microscope, he explained to the students the internal structure and operation mechanism of the giant algae spores.

"The teacher deserves to be a teacher. It's amazing!"

"Yes! Yes! Even the structure and function of giant algal spores are so well understood. It's amazing! "

Around the students, one by one with admiration, face full of admiration.

No wonder they marveled.

There are so many species in the world that even the top biologists and geneticists can't have a clear understanding of the cellular structure of every species.

The teacher's knowledge is vast.

Lu Li smiles, thinking: I am learning to sell now, cheating with extraordinary power to make it clear.

In the process of explanation, Lu Li's spirit consciousness has penetrated into the nucleus of the spore cell and witnessed the DNA sequence of the giant algae.

Consciousness fell on the DNA molecular chain of the giant algae, and Lu Li began to interpret the gene information of the giant algae.

With Lu Li's current knowledge, it is not difficult to interpret the genetic information of the giant algae after seeing the DNA molecular chain of the giant algae and experiencing the information expression.

After interpreting the gene information of the giant algae, Lu Li's spirit consciousness has completely remembered the gene information.

Today's Luli, spiritual consciousness has been integrated with the body, thoroughly integrated into every cell of the whole body.

After the gene information of the giant algae was memorized by the spirit consciousness, Lu Li suddenly felt as if I can replicate this genetic information in my own cells.

What does that mean? This means Luli can become a seaweed!

It turns out that Is that what you mean?

This is a kind of "real Metamorphosis", which is not just a "Metamorphosis" of imitating appearance, but a kind of reproduction from the level of gene, which essentially becomes another biological form.

That's interesting!

Lu Li smiles, and the spirit consciousness is separated from the spore cells in his hand. He doesn't want to turn into seaweed.

Understanding the "real deformation", let Luli harvest not shallow.

Druids in Western Fantasy are proficient in metamorphosis and can become various creatures. What birds and animals, fish, even can become a tree.

Now, my "true transfiguration" can completely achieve the level of Druid transfiguration.

Of course, this is not the time to think about it.

Lu Li smiles and focuses on the experiment in front of him.

After fully understanding the genetic information of the giant algae, Lu Li's genetic editing and improvement of the giant algae have been well established.Turning to look at Wenwan, Lu Li asked, "Wenwan, what kind of foreign gene were you going to add to the genes of the giant algae?"

"I've tried a lot."

"I've tried rice, corn, wheat, potatoes, sweet potatoes and even some fruits," she replied. But Not once. "

"Have you ever tried cactus genes?" Lu Li smiles at Wen Wan.

"Cactus?"

Wen Wan was surprised, "teacher, do you mean Use the cactus's nutrient storage mechanism to modify the genes of the giant algae and let it store nutrients on the leaves

"Yes

Lu Li nodded, "the marine environment is different from the land environment. It's more difficult to blossom and bear fruit. There are no bees and butterflies to pollinate."

"Ha ha!"

Wen Wan touched her head. "I forgot this!"

"In fact, it is not impossible to carry out gene modification from the seed direction."

"Take the sporophyll as a flower and use sea water to spread pollen," Lu said. However, in this way, it is more difficult to edit and modify genes, and there are more genes to be modified. "

"So..."

Wen Wan's face was full of helplessness, "I thought of two ideas, but chose the most difficult one?"

"Go ahead in the face of difficulties! The spirit is commendable Lu left a joke.

"Ha ha! We can make progress in the face of difficulties! "

The students beside us all laughed.

"What are you laughing at?"

Wen Wan's sister glared at the crowd. "What the teacher said is that it's difficult to meet difficulties. Don't think it's wrong!"

Now Even Lu Li laughed.

"Come on! Stop it

Lu Li waved his hand, "go and get a piece of cactus, succulent plants are OK, quickly extract genes! Let's all do it once. Let's go! "

"All right!"

All of them got up in a hurry to collect materials and prepare for the experiment.

Cactus is not rare. It doesn't even have to be cactus. All succulent plants can be used.

There are cactus samples in the biology lab. In the office, there are also succulent plants raised by gentle girls, all of which can be used for experiments.

A group of doctoral students swarmed in. A pot of succulent plants on the table of the gentle girl picked all the leaves in an instant, leaving only a bare pole.

"I'm so angry!"

Wenwan chopped off her feet and Cut off the poles of the succulent plants.

The experiment of extracting genes is very simple, which can be done by middle schools with better conditions, not to mention those doctoral students with special equipment.

A moment later, people came to Lu Li with a test tube full of succulent plant genes.

"Teacher, we're done!" Everyone reported to Lu Li.

"All right!"

Lu Li took a test tube from Wenwan's sister, took a little gene with a thin tube suction needle, and put it on the test bench.

"I'll give you a demonstration, and you'll do it yourself later."

Lu Li turned on the electron microscope, and the screen showed the genes of succulent plants.

"First of all, we need to analyze and interpret the genes of succulent plants, and determine which gene expression is the mechanism of nutrient storage."

Lu Li pointed to the screen, explained to the public, and selected the nutrient storage genes of succulent plants.

Pick up the gene probe, inject the gene target protein and gene transcription protein, and transcribe a piece of gene information representing the nutrient storage mechanism from the genes of succulent plants through transcriptase.

Next, Lu Li combined the transcription protein with the gene splicing protein, which transcribed the gene information, and then injected the gene into the spore cells of the giant algae.

Lu Li has interpreted the gene information of the giant algae for a long time, clearly understood the nutrient storage mechanism of the giant algae, and quickly found the location of the target gene fragment.

The target gene is injected, the gene position is locked, and the splicing protein combined with the transcription protein quickly moves to the position of the target gene segment.

The splicing protein cuts off the gene chain, loads the gene fragment transcribed in the transcription protein on the incision, and soon combines with the gene chain of the giant algae itself to form a new gene sequence.

The cleavage proteins and transcriptional proteins then decompose and become the nutrients of spore cells.

"If you do this, you're done."

Lu Li chuckled at the crowd. "Next, we have to wait until we cultivate the modified giant algae to determine the experimental results!"

"The teacher is so powerful!"

"Yes! The operation is too precise! "

There was a round of applause.

"Come on, don't flatter me!"

Lu Li waved his hand to the crowd, "according to the way I just did, do it yourself again."

"All right!"

Everyone went to the test-bed and did the experiment again according to the demonstration teaching of Lu Li just now.Lu Li turned around in the laboratory, watching the people carefully do the experiment.

Compared with Luli's precise and quick operation, these students who have no extraordinary perception ability to cheat are stumbling in operation, and they have succeeded in editing genes once or twice after ten times.

This is also the reason why Luli has developed new gene targeting technology and gene editing technology.

If we use the previous gene editing technology, it would be good to succeed once in a hundred times.

"That's it! Do the experiment slowly

Lu Li said hello to the crowd, turned and walked out of the laboratory.

According to Lu Li's judgment, the experiment on gene editing of the giant algae was definitely successful.

However, to verify the experimental results, we have to wait until the genetically modified seaweed is cultivated.

For the genetic improvement of the giant algae, it is certainly not perfect at one time.

The main problem is After gene editing, the giant algae will be eaten as food.

There is a question of whether it is delicious or not!

kelp is rich in nutrients, rich in potassium, iodine, amino acids and trace elements, can reduce the incidence rate of cold, and can improve the physical strength and fatigue resistance of the elderly.

The mechanism of nutrient storage was changed. The giant algae with thick leaves also deposited a lot of starch, protein and algal gum in the leaves.

It can definitely be used as food.

As for whether it tastes good or not, this Lu Li is not sure.

He walked out of the lab and came to the parking lot outside. Assistant Tian opened the door and came up.

"Professor Lu, you stayed in the gene lab for four hours today."

Assistant Tian opened the door of the car for Lu Li and got on the car. He said, "are you going to study the new technology in genetics?"

He has been Lu Li's assistant for a long time, and he is very familiar with Lu Li. Tian's assistant is not so rigid, serious and serious, and his words become more casual.

"Yes

Lu Li nodded, "I've just finished the experiment with my students. I'm going to farm in the ocean!"

"Well "Farming in the sea?"

Assistant Tian was stunned for a moment. When can he farm in the sea?

Well, you are the most powerful scientist in the world. You can farm on the moon!

"Is it strange to farm in the ocean?"

Lu Li smiles, "there are plants in the ocean, too!"

"This..."

Tian Zhu drove out of the parking lot and said, "what kind of wheat can be planted in the ocean?"

"Haimai Lu Li laughed.

"You Have you really developed wheat that can be grown in the ocean

Assistant Tian widened his eyes, "my God! How high does it take for wheat to grow from the bottom of the sea

"At least 80 meters, generally one or two hundred meters, and the longest is more than 500 meters!" Lu Li answered seriously.

"Five hundred meters of wheat?"

Assistant Tian couldn't help exclaiming.

"Well, no kidding!"

Lu Li smiles and shakes his head. "It's not wheat, it's seaweed. This kind of giant algae can grow up to 500 meters. I improved it with genetic technology to make it produce food. "

"Let seaweed produce food?"

Tian assistant Leng for a long time, just hold out a sentence, "fierce!"

You can make seaweed produce food. Will you let roosters lay eggs next time?

Later Will men have children?

Assistant Tian shivered all over. You scientists, it's terrible!

If Lu Li knew what assistant Tian thought, he would tell him that it was difficult for roosters to lay eggs?

Lu Li leans on his seat, but he is thinking: Seaweed makes food. It's really meaningful!

Our country uses 7% of the world's arable land to feed a quarter of the world's population!

Grain For us, never too much!

Why can we eat all kinds of animals as protective animals? Because we are afraid of hunger in history!

Once the experiment is successful, it will be of great significance to our country's food strategic security!
