“Living” is a chemical process. Since Stamets was able to transfer the DNA into himself, he had identified the segments that coded the particular proteins.
He was such a a quitter. One suicide and he gave up. He just needed to jump back and give her a motivational speech when she was a child and presto! Timelord Victorious!
Now he has the ability to see time a little differently due to that DNA
Which is kind of weird given that DNA is carbon, hydrogen, etc, moving and forming bonds based on physics. It’s why folding at home can simulate proteins.
So anything DNA does can be simulated on a computer.
That didn’t stop Bashir’s parents. If regular parents can make it happen it for their below average child, a Dr Noonian Soong type will be all over it.
