Confirmation of results demonstrated that new DNA was working and expressed genes in the animal.

Embryonic stem cells provide a means to transfer new DNA into the germline.

Unlike normal cells, cancer cells are constantly dividing and thus need to make new DNA all the time.

He showed that over time, the new DNA became integrated into almost all somatic cells tested.

Now only the cells that have the new DNA can grow.

The new Japanese DNA isn't based on race.

When the cells replicate, they pass on the new DNA as well.

The enzymes then help generate new DNA to replace the damaged fragments.

This new DNA is then incorporated into the host's genome by an integrase enzyme.

The new DNA took root in the egg and directed it to develop into an embryo.
