In the polymerization of DNA, a phosphodiester bond is formed between a phosphate group of the nucleotide being added and ________ of the last nucleotide in the polymer.

Question

Quizplus · Accepted Answer

A phosphodiester bond is formed between the phosphate group of the nucleotide being added and the 3' hydroxyl (OH) group of the last nucleotide in the polymer. This forms the backbone of the DNA strand. The 5' phosphate group of the nucleotide being added is also involved in the bonding process, but it does not directly bond with the last nucleotide in the polymer. Nitrogen-containing bases also play a role in DNA polymerization, but they do not participate in the formation of phosphodiester bonds.
