Question

in a nucleic acid polymer, the bonds that help to hold double - stranded regions together occur between what parts of the nucleotide monomers? view available hint(s) nitrogenous bases sugars and phosphates sugars nitrogenous bases and phosphates amino acids

Explanation:

In nucleic acid polymers like DNA, the double - stranded regions are held together by hydrogen bonds between complementary nitrogenous bases (adenine pairs with thymine or uracil, and cytosine pairs with guanine). Bonds between sugars and phosphates form the backbone, not the bonds holding the two strands together. Sugars alone and nitrogenous bases with phosphates are not involved in this inter - strand bonding. Amino acids are related to proteins, not nucleic acid strand bonding.

Answer:

A. Nitrogenous bases
