Formation of Deoxyribonucleotides
― The typical cell contains 5 to10 times as much RNA (mRNAs, rRNAs and tRNAs) as DNA. Therefore, the majority of nucleotide biosynthesis has as its purpose the production of rNTPs. However, because proliferating cells need to replicate their genomes, the production of dNTPs is also necessary. This process begins with the reduction of rNDPs, followed by phosphorylation to yield the dNTPs. The phosphorylation of dNDPs to dNTPs is catalyzed by the same nucleoside diphosphate kinases that [...].
