The scientific inquiry or scientific method is a systematic approach used in means of acquiring new knowledge and it is not just a rigid sequence of steps because they are made uniquely in which the way that they are being followed is based on the problem that is trying to be solved that makes it something that is not a rigid sequence.
Nucleotide substitutions in a gene occur at a relatively constant rate.
A nonsynonymous substitution is a nucleotide mutation that alters the amino acid sequence of a protein. Nonsynonymous substitutions differ from synonymous substitutions, which do not alter amino acid sequences and are (sometimes) silent mutations.

Hope this helps you, and happy studying~!
