Maybe one day they'll remove the latent virus code in our DNA and use those areas up for DNA Storage. Imagine if every human that went into space to colonize, had a library of information in their finger tips.
Question: with latent virus code removed, does the cell use less energy to replicate or is able to replicate faster?
In theory it should, and substantially, since DNA replication is a highly energy dependent process. In practice we can’t just nilly-willy remove genetic material from our chromosomes, even if it ostensibly has no useful function. That said, scientists have attempted long-range deletions in mouse and some of those show no phenotype (within the highly limited study!). But as far as I know they didn’t look at energy expenditure.
