Which of the following statements correctly identifies the location of the hydrogens bonds in DNA
asambeis [7]

Answer:

This question is incomplete as it lacks options. However, it can be answered based on general knowledge of the DNA structure.

Hydrogen bonds in a DNA are located between the nucleotides that holds the double stranded DNA molecules.

Explanation:

Deoxyribonucleic acid (DNA) is the genetic material in living cells. The DNA molecule is made up of nucleotides monomers. However, since the DNA molecule is double-stranded, the nucleotides are of two chains composed of four nucleotide subunits viz: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).

The two chains of nucleotides in a DNA molecule are called strands. Each strand is bonded to one another by the nucleotides using complementary base pairing i.e. A-T, G-C. The bonds between the nucleotidew of each strand is called HYDROGEN BOND.

Hence, HYDROGEN BONDS in a DNA molecule is located in between two nucleotides of each strand. That is, hydrogen bond holds Adenine to Thymine and Guanine to Cytosine.
