WebNucleotide synthesis is an anabolic mechanism generally involving the chemical reaction of phosphate, pentose sugar, and a nitrogenous base. Degradation of nucleic acids is a catabolic reaction and the resulting … WebDNA polymerase is the primary enzyme which catalyzes the linking of the 3′ hydroxyl group of the end nucleotide to the 5′ phosphate of nucleotide to be added.

Web28 apr. 2016 · During polymerization of nucleotides to form nucleic acids, the hydroxyl group on the phosphate group attaches to the 3’ carbon of a sugar of one nucleotide to form an ester bond to the phosphate of another nucleotide. The reaction forms a phosphodiester linkage and eliminates a water molecule. Figure 1: Phosphodiester bond … WebIn a cell, a nucleotide about to be added to the end of a polynucleotide chain will bear a series of three phosphate groups. When the nucleotide joins the growing DNA or RNA chain, it loses two phosphate groups. So, in a chain of DNA or RNA, each nucleotide has just one phosphate group. Polynucleotide chains WebThe synthesis of RNA is performed by enzymes called RNA polymerases. In higher organisms there are three main RNA polymerases, designated I, II, and III (or sometimes … helm ink pink
