One month later.
Unknowingly, time has entered winter from late autumn.
In late January, the final exams for various subjects are coming one after another, and the campus is filled with the atmosphere of vacation and the joy of enjoying hardships.
In Shangdu, dark clouds formed by warm and cold air masses enveloped the sky throughout the southern region of Central Continent. Snowflakes began to appear in the Yangtze River Basin, and the meteorological observatory also issued a cold wave warning.
At this time, Chen Chen, who was in the library, had just put down a copy of "Lippincotts Illustrated Reviews: Biochemistry" and took a deep breath.
This means that a month of dark study plans is finally over.
Of course, this is only the first stage.
In the past month, Chen Chen not only completed knowledge points in several subjects such as cell biology, microbiology, molecular biology, biochemistry, and genetics, but also went deep into the field of stem cells and biochemistry, raising it to the master's level, and proposed several Imagine.
For example: "Cut the medulla oblongata of the experimental subject to separate the head and neck, and then use autologous neural stem cells for treatment. Is it possible to reconnect the nervous system while maintaining the physiological functions of the experimental subject?"
Another example: "Using radiotherapy and chemotherapy to destroy senescent stem cells in the bone marrow of elderly experimental subjects, and then using the 'homing function' to inject autologous hematopoietic stem cells and mesenchymal stem cells cultivated in vitro to rebuild the immune system. Can some organs of the elderly experimental subjects be regenerated?" Rejuvenating?”
Another example: "Can the cranial nerves be reconstructed by removing part of the experimental subject's brain and using autologous neural stem cells to create a framework model?"
Chen Chen feels that adult stem cells alone have a lot to offer.
If you give yourself a laboratory at this time, let yourself go and do a few experiments, and then publish a few sci papers, you can easily make your debut in the biological academic world. This is called a sure blow.
But I can't.
Chen Chen thought silently. It was unrealistic for him to start a project now. He was just a freshman. Not to mention that the school would not give him the right to start a project. Not even the professors' research groups would want him.
If you can't do experiments yourself, you can't write papers, and you can't get ahead in the field of scientific research.
Chen Chen couldn't help but frown, he didn't have much time.
But at this moment, Chen Chen suddenly noticed someone beside him poking his arm with a finger.
He remembered that the person next to him usually had some familiar faces after staying in the reading room for a long time, and the person next to him was a girl from the School of Biological Sciences, and he could often see her checking out related books.
But she must be a senior, because she can always be seen frozen on the computer screen on the interface of her graduation project.
"Hello, I saw you were reading a book about biochemistry. Can I lend you a moment to ask a question..."
The girl opened her eyes wide and bit her lip, asking a little guiltily.
"You ask." Chen Chen closed the book in his hand and looked at the other party calmly.
Facing Chen Chen's gaze, the girl unconsciously avoided Chen Chen's eyes.
As early as a week or two ago, the girls noticed Chen Chen's arrival. Although this man did not have a handsome appearance, he still attracted the attention of many people.
Not because of anything else, but because the man in front of him had an indescribable smell.
It was an aura in which everything was under control. Every movement and expression seemed so magnanimous and confident, especially his eyes, which seemed to contain a sea of stars.
Handing over the exercises in her hand, the girl carefully moved the stool to Chen Chen's side, waiting for Chen Chen's explanation from a safe distance like a baby.
There was a faint fragrance coming from the girl's body. It was the smell of a high-end perfume. Chen Chen glanced at it subconsciously, and then lowered his head to look at the subject.
[There is a polypeptide whose primary structure may be linear or closed-loop. Please identify it as simply as possible and write a detailed plan?]
"This question is very simple."
Chen Chen thought for a moment and then said, "Use 6 moles of hydrogen chloride per liter or 4 moles of sulfuric acid per liter to reflux for 20 hours to obtain the L-type amino acid without causing racemization. Analyze its amino acid composition, and then based on the amino acid composition Select the appropriate proteolytic enzyme for hydrolysis of the composition. If it fails once, try a few more times... "
"Then use the original sample as a control to perform polyacrylamide gel electrophoresis to separate proteins and oligonucleotides... You should know next, right?"
The girl nodded repeatedly, showing a look of surprise.
"It is better to take less estazolam."
Chen Chen warned, pointing to his head, "This thing will affect your thinking."
"how do you know… "
The girl was stunned when she heard this and asked in surprise.
"Although you are covering your face with glasses, if you look carefully, you can still see that your face is slightly swollen."
Chen Chen explained softly, "At the same time, your eye circles are too heavy, your eyes have increased bloodshotness, and your skin has strong oil secretion. These are all side effects of taking estazolam. There is this case in the book I just read."
"Okay, okay..."
The girl smiled awkwardly and felt like crying.
"Ahem!"
There was a cough from the front row, which seemed to remind them that the conversation in the library was a little too loud.
"If you can, you have to find a way to stop sleeping pills,"
Chen Chen continued, "Otherwise you won't be able to survive the postgraduate entrance examination re-examination."
"You know I want to take the postgraduate entrance examination?" The girl was even more surprised.
"The list of graduate students will be released at the beginning of the first semester of your senior year. If you are successfully admitted, you will not take estazolam and you will not ask the question I just asked."
Chen Chen continued to explain, "Besides, a bachelor's degree in the Department of Biology is of little use. At least a master's degree is of some use. People who are slightly motivated will choose to continue their studies, so you have only one way to go: postgraduate entrance exams."
The girl was about to burst into tears, "I'm too stupid. I couldn't pass the postgraduate entrance examination even though I worked hard, and I basically failed in the preliminary examination..."
"You want to take the exam at this school. I suggest you seek advice from classmates with good grades. Don't waste time on your graduation project. If you still can't pass the exam... you can wait until next year to take the exam again."
"Ahem!"
There was a heavy cough from the back row.
"But what should I do if I can't write my graduation project?"
The girl pursed her lips and started talking completely, "Also, I'm just waiting to become a graduate student to show my dad. If I don't pass the exam the first time, I may not have the patience to continue taking the exam..."
"Are you just impatient?"
Only then did Chen Chen take a serious look at the girl. She was not ugly, but she didn't have any makeup and wore a pair of black-rimmed glasses, which made her look a bit out of place.
However, if you look at her clothing brand, you wouldn't think so.
Although the girl is wearing dark casual clothes, if you look closely, you can see that they are all Celine Hermès and the like, and even her computer is an alien brand.
Even her long, satin-like hair cannot be washed out with ordinary shampoo.
"Actually, there is still hope."
Chen Chen pondered for a while and then said again, "Students who have outstanding scientific research and academic achievements during their undergraduate years, or students who have participated in large-scale subject competitions and achieved outstanding results, can apply for postgraduate qualifications based on their academic expertise."
"Academic expertise guarantees postgraduate study?"
The girl murmured in a low voice. She had just raised her hopes, but then her face fell down again, "But even if I join the mentor's project team, the project team has outstanding scientific research results, and I won't get a single work..."
Chen Chen shook his head and chuckled, "If you have enough financial resources, you can rent a laboratory outside the school. I happen to have a few experiments. If they succeed, I can give you one."
"you?"
The girl looked wary when she heard this and moved back unconsciously, "Why don't you go to your instructor if you want to do an experiment?"
"I haven't been assigned a mentor yet."
The girl's eyes suddenly widened. She pointed at a pile of English materials in front of Chen Chen, "Are you a freshman?"
"Ahem!"
There was a cough from both sides at the same time.
"Class 2 of the 20th grade of Biology, my name is Chen Chen."
Chen Chen took out his campus card and shook it, "Forget about the school's laboratory. The few experiments I want to do are at least monthly. I'm not a professor, and the school can't let me occupy it for so long."
"But you are only a freshman..."
The girl was a little moved, but also a little hesitant, "Are you the top student at Zhiyuan College?"
"No." Chen Chen shook his head.
"Then how can I trust you to help me?"
"I'm just making you a proposal. If you don't believe me, there's nothing I can do about it."
Chen Chen said indifferently, and then turned his eyes to the book in his hand again.
