Chapter 65 (2/2)
Shen Xue did not mention this topic again.
She knows that Zhou Wen is a very smart person, just don't show it, some things just stop.
The two chatted with each other, and soon Zuo Mengmeng joined in.
Two women and one man, until late at night.
……
On the morning of the 31st, as soon as Zhou Wengang arrived at the hospital, Professor Wang Huiyao called to ask for his opinions in order to hold the second thesis defense meeting.
Zhou Wen has no comment.
That was his duty.
A patent has been applied for the genetic transformation technology of rice aphids.
Passing the defense meeting can make patent technology examination and approval easier.
Zhou Wen hung up after the appointment of the second debate time.
Who knows the bell rings again, take a look, it is sister-in-law calling.
”Hello, Lao Zhou. Is it convenient for you now?”
”Well, convenient. What's the matter?”
”I'd like to ask you a little favor.”
”Say it.”
”It's like this...”
After Chen Zhiyuan finished speaking, Zhou Wen knew the whole story.
Chen Zhiyuan and his primary school classmates had dinner together last night. Maybe they drank too much. His classmates told him make complaints about the fact that his son was not like him.
Chen Zhiyuan is also big mouth, said that his hospital knows people, can help him do a DNA identification.
And today his classmates called him.
Zhou Wen said: ”since he is not at ease, you let him go directly to the testing agency. Now the technology is very advanced. If you hurry up, you can get the test report within 24 hours. ”
Chen Zhiyuan said: ”I know, this is not he said there are psychological disorders, want to have a psychological preparation, if there are really problems, then go to professional testing institutions to do.”
”It's really farting when you take off your pants.”
Zhou Wen said sadly that he is going to do drug preparation experiment today. If you do DNA testing, you can't do anything today.
However, his sister-in-law seldom asks him for help, which is sure to help.
He was just about to speak when he heard the sound of a task.
Another small task.
Nothing is better than nothing.
Zhou Wen did not go to see the specific task content, said: ”OK, you let him send the inspection materials. In addition, you tell him that I don't issue a test report. ”
Chen Zhiyuan was overjoyed when he heard the speech and said, ”good, good, no test report.”
After a pause, Chen Zhiyuan said, ”I'll accompany him to the past, and I'll be there in about an hour.”
”Well!”
At half past eight, Chen Zhiyuan arrived in a black car.
May be sorry, Chen Zhiyuan that classmate did not get off the bus from the beginning to the end.
Chen Zhiyuan gave Zhou Wen the blood stains and hair he had collected, and then whispered: ”I am an official in my classmate's family. I want to ask him to help me find a job with less money and more money.”
Zhou Wen secretly said, no wonder his sister-in-law is so enthusiastic, glanced at him, ”do you still need to work?”
Chen Zhiyuan was not angry and said, ”Lao Zhou, what you said is that I am also a young man who has ideals, aspirations and pursuits? It has never been my creed to eat and die... ”
”OK, OK, your life creed says to Xiao Lingling ~” Zhou Wen said to turn around and go, ”I'll tell you the result tomorrow.”
”Well! I'll send you the kit money back. ”
Zhou Wenpai waved his hand, ”no ~”
”how can I do that! Let's go one size at a time. ”
Chen Zhiyuan knows that a kit for DNA identification costs 1000 yuan. He can't ask Zhou Wen to give this money.
”You don't have to. Biochemical blood test is always using my DNA. I didn't ask them for money. What's wrong with a kit? ”
Finish saying with way: ”OK, you go.”
After saying goodbye to Chen Zhiyuan, Zhou Wen went straight to the PCR laboratory.
Zhou Wen has already done the genetic test once. This time, he is still familiar with it.
The first step is to extract DNA.
The second step was PCR amplification.The first two steps are the same as those for mouse DNA amplification.
The third step is slightly different. We need to add some internal standards for detection to the amplified DNA to mark the length of the detected fragment.
The fourth step should be run electrophoresis, capillary sequencer detection.
Finally, the data are analyzed.
There are 23 pairs of chromosomes in human, each pair is two, from the father and mother respectively.
When testing, as long as a certain number of DNA ”sites” are tested, if they are the same as the parents, then they are biological, otherwise there is doubt.
If one or two ”loci” do not match, we need to do some additional site detection, because there is the possibility of gene mutation.
If more than three ”loci” do not match, it is not a parent-child relationship.
Zhou Wen lived from 8:30 a.m. to 6:00 p.m. for 10 hours.
It's done.
After analysis, it was found that the six loci of d21s11d18551d16s5399vwad12s391 pentae were different in the two samples.
In other words, Chen Zhiyuan's classmates have absolutely no blood relationship with his son.
It's another story of an honest man picking up the plate.
It could also be ”stoppage”
