BOTH POSITIVE AND NEGATIVE SELECTION PRESSURES CONTRIBUTE TO THE POLYMORPHISM PATTERN OF THE DUPLICATED HUMAN CYP21A2 GENE.

Both positive and negative selection pressures contribute to the polymorphism pattern of the duplicated human CYP21A2 gene.

The human steroid 21-hydroxylase gene (CYP21A2) participates in cortisol and aldosterone biosynthesis, and resides together with its paralogous (duplicated) pseudogene in a multiallelic copy number variation (CNV), called RCCX CNV.Concerted evolution caused by non-allelic gene conversion has been described in great ape CYP21 genes, and the same con

Codon usage patterns across seven Rosales species

Abstract Background Codon usage bias (CUB) analysis is an yale law school colors effective method for studying specificity, evolutionary relationships, and mRNA translation and discovering new genes among various species.In general, CUB analysis is mainly performed within one species or between closely related species and no such study has been app
