Abstract. Most molecular evolutionary studies of natural selection maintain the decades-old assumption that synonymous substitution rate variation across sites within genes occurs at levels that are either nonexistent or negligible.

This example shows how to estimate synonymous and nonsynonymous substitution rates between two nucleotide sequences that are not codon-aligned using maximum likelihood method. This example uses two nucleotide sequences representing the human HEXA gene (accession number: NM_000520) and mouse HEXA gene (accession number: AK080777).

Further, WOLFE, SHARP and LI (1989) showed a correlation between the rate of synonymous substitution and the G + C content in a comparison of the nuclear genes of rat and mouse.

This inconsistency could potentially be resolved through a more complete characterization of genes’ synonymous substitution rates and through a dis-section of which genes have the most repeatable synony- Short Communication Massive difference in synonymous substitution rates among mitochondrial, plastid, and nuclear genes of Phaeocystis algae David Roy Smitha,⇑, Kevin R.

9 Aug 2007 A synonymous site substitution is defined as a change in a protein-coding gene that does not alter the amino acid sequence encoded by the gene  Method, Substitution rates are calculated per synonymous site per year based on externally calibrated divergence times. These divergence times relate to  Synonymous Substitution Rates Differ in the Luciferase Genes of P. lunula and As can be seen, the rate of synonymous substitution for the first 126 codons is  onymous and nonsynonymous substitution rates are cor- related in mammalian 1989) that the synonymous substitution rate is close to the mutation rate. In fact  16 Feb 2007 Changes in synonymous substitution rates can reflect changes in generation time or mutation rate, while nonsynonymous rates can also be  Previous studies have estimated that, in angiosperms, the synonymous substitution rate of chloroplast genes is three times higher than that of mitochondrial

Actually, when the rate of nucleotide substitution is the same for all evolutionary Therefore, the rate of synonymous substitution is usually higher than that of 

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. As nonsynonymous substitutions result in a biological change in the organism, they are subject to natural selection.
