Can you mix human And animAl DNA?


Its eminently possible. Although different animals normally have different genes and arrangements of chromosomes,the molecules or DNA and RNA are common to all living things.

Cell biologists can inserts DNA from 1 organism into the chromosomes of another using a variety of techniques , including viral vectors and physically injecting into the cell nucleus.

When animal embryos are injected with whole human stem cells. DNA from 1 organism has been shown to cross into the cells of the other. This has important repercussions for the way disease such as AIDS and flu are studied, especially how they emerge and spread.
