Biochemical characterization of the p51 sub-unit of human immunodeficiency virus reverse transcriptase in homo- and heterodimeric recombinant forms of the enzyme.

abstract：:It is clear that G1-S phase control is exerted after the mouse embryo implants into the uterus 4.5 days after fertilization (E4.5); null mutants of genes that control cell cycle commitment such as max, rb (retinoblastoma), and dp1 are embryonic lethal after implantation with proliferation phenotypes. But, a number of ...
