Answer:
b. Nucleotides
Step-by-step explanation:
The process mentioned above refers to the nucleotide bond in the process called phosphodiester bonds.
At such linkages, the nucleotides are linked to form phosphate bridges to each other. The pentose carbon-3 hydroxyl group (5-carbon sugar) of the first nucleotide joins the second nucleotide pentose carbon-5 hydroxyl-linked phosphate group via the phosphodiester bond. In this way, the nucleotides join together, constituting a deoxyribonucleic acid ribbon.
