...The stem of a nucleic acid might be conserved, but not the sequence....
A natural gene has a rate of utilisation of an aminoacid codon of around 0.5%, tops.
...There is a thing called Minimal Genome Concept, i.e., the minimal number and type of genes necessary to be present in the bacterial genome in order to maintain them alive.
If you totally disagree with any of these statements or would like to add anything to the SmartAss chapter of the Detoxifying Notes' Label, please reply by commenting to the post. I would like to understand the second statement a lot better, it is actually something I heard on a meeting but couldn't figure out much.
