description
Nucleosides and free bases generated by DNA and RNA breakdown are converted back to nucleotide monophosphates, allowing them to re-enter the pathway of purine biosynthesis. Nucleosides and free bases generated by DNA breakdown are converted back to nucleotide monophosphates, allowing them to re-enter the pathway of purine biosynthesis. Nucleosides and free bases generated by RNA breakdown are converted back to nucleotide monophosphates, allowing them to re-enter the pathways of purine biosynthesis. Under normal conditions, DNA turnover is limited and deoxyribonucleotide salvage operates at a correspondingly low level (Watts 1974)
