Intragenic Hill-Robertson interference influences selection intensity on synonymous mutations in Drosophila.

Abstract excerpt

Natural selection influences synonymous mutations and synonymous codon usage in many eukaryotes to improve the efficiency of translation in highly expressed genes. Recent studies of gene composition in eukaryotes have shown that codon usage also varies independently of expression levels, both among genes and at the intragenic level. Here, we investigate rates of evolution (Ks) and intensity of selection...
