Human DNA Hu question, the similarity of human and human DNA is 72 1 ? Why is this happening?

Can human DNA be extracted from blood?

Yes, there are cells in the blood, and there is DNA in the cells

Will someone else have someone else's DNA information if they transfuse blood into themselves?

If it's just a blood transfusion, then there will be a period of time at first, but over time, these cells will gradually die, and there will be no DNA information. If it is a bone marrow transplant, it will transfer other people's hematopoietic stem cells, so you can produce cells that are the same as the DNA of this hematopoietic stem cell, and you will have someone else's DNA information on you.

Hope mine is helpful to you!

1. It can be found in the blood, but very little. It takes many steps to purify.

Nails can't. Hair follicles are used for hair.

2. A very small probability event multiplied by a very small probability event will almost never happen.

Theoretically, there will be a little bit. But only temporarily. Because the lifespan of blood cells is shorter. Maintain bodily functions for a period of time and then die. Your own hematopoietic stem cells then produce new blood cells.

Human and human DNA?

Could it be that the premise of this question is that humans are different species?

If it's the DNA similarity rate between people, it's not mistaken.

The Human Genome Differences Map shows the nuances of the genomes of 270 individuals from Nigeria, United States, China, Japan. Ninety percent of the human genes are the same. Human genome differences are the study of base differences between single nucleotides, the basic building blocks of DNA.

Of course, each person's genome is different, and even for a certain individual, there are many kinds of genetic mutations going on in the human body at any time, and every cell in each person's body has tens of thousands of bases or base pairs that mutate every day, and there are many reasons.

But important functional genes have been the same for all people and even many organisms for hundreds of millions of years, otherwise important genes will die early if they are mutated. The results of studies are often published on the genes of one or several people in multiple subjects, and it is not known to anyone except the scientists and the people involved. So the human genome is only the genome of the individual.

Scientific research is focused on important genes, including all kinds of organisms.

Even if there are perfect genes, at the current level of human beings, they can't even understand the basic problems of genes, such as the famous example of the prokaryotic promoter, of course, it is impossible to consider perfection. For example, if you say that Jordan can't be said to be perfect in basketball, and he can't fly, others won't mention it.

According to the Human Genome Project, there are about 20,000-25,000 genes in a human DNA molecule, with a total of 300 million base pairs.

Everyone's DNA is different, but they have a certain amount of similarity, which is why everyone is human, but they look different.

It is the whole of the person, because the jujube is a part of the human body and carries all the genes of the stool elimination man, and it can be copied out of the human bridge, but the genes in the beard must be introduced into the living cells with high technology to extract the genetic material in the nucleus and culture, but the mitochondria in the living cells also have a part of the genetic material, so it is necessary to choose their own living cells to replicate the exact same person. However, it is better to culture it directly with its own live cells.

The beard contains a full set of genes of the human body, and according to the research of scientists on cloning for many years, it may be an important conclusion that the nucleus of the animal code ear is totipotent. See.

If you store it with TE, the fragment DNA can be stored at -20 degrees for 1-2 years, and the plasmid DNA can be stored at -20 degrees for several years.

It's almost all of the people, but you can't take out and copy the people, and the way you say it will stay for a day at most, so give up.

Anyway, the DNA sequence is cracked. The role of which gene on the DNA is basically clear. However, it has been found that there are many fragments of human DNA that do not seem to be useful and do not constitute genes. Later, there were also studies that said that there were some useless fragments and some other effects.

What exactly is the origin of humanity? How much information have we deciphered in our DNA? _x264

First of all, it should be made clear that gene is not an abstract concept, but a concrete substance, the genetic material of the human body. Genes are found in every cell of the body because genes are genetic material. So no matter what organ of the body, which part of the tissue has genes in it.

Inside the nucleus of each cell.

In plants, genes are in the nucleus, mitochondria, and chloroplasts.

Note: Root cells and stems of some plants do not have chloroplasts (both have nuclei and mitochondria, i.e.: every cell of the plant has genes).

In animals, genes are in the nucleus and mitochondria.

Note: Not every cell has !!

For example, mature red blood cells in the human body do not have a nucleus and no mitochondria, so there are no genes!

Of course, the genes are in the cell. Every cell has the genetic material in the nucleus of the 94 geno.

Every cell has a gene in the nucleus.
