If you want to alter the genome of an already living creature I guess that you have to change every cells. I'm not sure if it's possible.
However, a virus seems to be the perfect tool (it modify your genome to copy itself and infect other cells).
- tdaltonc 11y agoYou only need to alter it in the cells you care about.
- ldehaan 11y agoDNA doesn't vary by cell, and the method of introduction is chemical, I imagine this creates a chained effect, otherwise how would cells pass on activated chains through the body when your DNA naturally changes.
- toufka 11y agoThe DNA of a body does not naturally change (in any organized way). Cells pass on changed DNA only to their progeny. Only genetic changes to gametes will be passed on genetically to children. However, the regulation of DNA can be transmitted. One can turn genes on and off throughout the body by exposing the cells to particular signals such as hormones. But those don't change the DNA, they just change the interpretation and usage of the DNA that's already present.
- eggie 11y agoThe DNA does vary cell by cell. How does cancer come about if not?
