What animal's genes are closest to humans?

The genetic similarity between chimpanzees and humans is over 96%. Although the genes of orangutans and monkeys are most similar to those of humans, these two animals are limited in number and expensive. Animals such as rats, dogs and pigs share 85% ~ 95% physiological activity genes with humans, and the prices are relatively cheap. Therefore, pigs that are relatively easy to obtain and close to humans are often selected as the utilization targets in clinic.

Both of them belong to the genus Chimpanzee, and from the genetic point of view, bonobo and human * * * share about 98.7% DNA, bonobo and chimpanzee * * * share about 99.6% DNA, and about 1.6% gene is human and bonobo, not.

There is another study about their intimacy with other primates and humans. Archaeology tells us that the genus Gorilla evolved independently about 6.5438+0.4 million years ago, and the genus Gorilla evolved independently about 6.5438+0 million years ago. The ancestors of human beings separated from the ancestors of bonobos and chimpanzees in Africa 7 to 4 million years ago.

Genes (genetic factors) are all nucleotide sequences needed to produce polypeptide chains or functional RNA. Genes support the basic structure and expression of life. It stores all the information about race, blood type, gestation, growth and apoptosis of life. The interdependence of environment and heredity deduces important physiological processes such as life reproduction, cell division and protein synthesis. All life phenomena such as birth, growth, decline, illness, old age and death of organisms are related to genes. It is also an internal factor that determines the health of life. Therefore, genes have dual attributes: materiality (mode of existence) and information (fundamental attribute).

DNA fragments with genetic information are called genes and other DNA sequences, some of which directly work with their own structures, while others participate in regulating the expression of genetic information. It takes at least 265 to 350 genes to make up a simple life. (This involves the power of the gene working group. The human gene working group is basically similar to the fruit fly.)
