No, I'm done here - my assessment was entirely correct. You do not enter the discussion in good faith. I doubt you are capable of discussing the issue in good faith, based on your record of repeated and deliberate distortion here.
This is your statement....homologs such as the protamines may well have served some entirely different function before doing what histones do now. A minor change to that homolog, and presto - histones
"A" is singular. Now protamines and protamine analogs are only relevant to this discussion in light of your fiction. Thus they are mentioned by you as a possible candidate homolog. If not, then you deserve to have your red herring flushed down the toilet.
And I am now almost certain that you can't provide the sequences of the synthetics.
