Final answer:
The interaction of two strands of DNA via hydrogen bonds leads to the formation of the double helix structure, made of nucleotide polymers with a sugar-phosphate backbone and paired nitrogenous bases held together by hydrogen bonds.
Step-by-step explanation:
The interaction of two strands of DNA via hydrogen bonds results in a structure called the double helix. This structure resembles a twisted staircase, where the hydrogen bonds function like the steps that connect the two strands, or polymers, of nucleotides. Each strand is comprised of a sugar-phosphate backbone with attached nitrogenous bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). The bases pair specifically (A with T, and G with C) via the hydrogen bonds, maintaining the structure of the DNA.
In the context of the DNA structure, the terms genome and chromosome refer to different things. A genome encompasses all the genetic material of an organism, including multiple chromosomes, which are organized structures of DNA and protein that make it possible to efficiently package the DNA into cells. Therefore, the correct answer to the question is B. double helix.
