Webb7 okt. 2024 · Ribose (pictured) is the sugar in ribonucleotides, which make up RNA. One hypothesis for the origin of life on Earth is that life began with self-replicating RNA molecules. However, ribose is just one of many similar sugars. How ribose was naturally selected as the only sugar in RNA is an open question. WebbPARP proteins are highly conserved homologs among the eukaryotic poly (ADP-ribose) polymerases. After activation, ADP-ribose polymers are synthesized on a series of ribozymes that use NAD+ as a substrate. PARPs participate in the regulation of various important biological processes, such as plant growth, development, and stress …
