Yet just as epigenetically imprinted experiences from the lives of past generations can alter how genes are expressed in the present, gene therapies can repair faults in expression whether developed within a person’s lifetime or propagated and accumulated over many generations, without altering the DNA…
Other gene therapies include using ‘tamed’ viruses to insert missing genes
into defective cells. Although the virus
is manipulated in order to remove or reduce its toxicity and replicating
abilities, this technique corrects cell defects, rather than trying to build
new hybrid lifeforms with genes spliced from various sources in order to
produce a tailored artificial product.
Nothing’s ever black and white
