Question

What is meant by an “evolutionarily accepted mutation” and why this might be a more informative approach to think about the relatedness of codons in the genetic code that using the biochemical and biophysical properties of amino acids.

Answer 1

Evolutionary accepted mutations is the point mutation in the coding that is accepted by natural selection and results in increased fitness of the organism so it gets evolutionary accepted.

Mutations occur in genetic code that determine the protein structure so to think about the relatedness of codons in the genetic code that using the biochemical and biophysical properties of amino acids will tell us the point of mutation and can be used as molecular clock.
