摘要: Analysis of the rate nucleotide substitution at silent sites inDrosophila genes reveals three main points. First, varies (by a factor two) among nuclear genes; it is inversely related to degree codon usage bias, and so selection synonymous codons appears constrain in some genes. Second, mitochondrial may have evolved only as fast with weak bias (and two times faster than high bias); this quite different from situation mammals where evolve approximately 5–10 Third, absolute about hihger average mammals.
