In which of the following hydrogen bonds can be found? A. Between cytosine and thymine in a DNA double helix
B. Between deoxyribose sugar and nitrogen base in a DNA nucleotide
C. Between deoxyribose sugar and phosphate group in a DNA nucleotide
D. Between purine and pyrimidines bases in a DNA double helix

C. Between deoxyribose sugar and phosphate group in a DNA nucleotide.

Explanation:

Hydrogen is a very important element in the planet due to the many uses of its compounds for example, water. Hydrogen is also very important to humans as it is integral to DNA formation.

Hydrogen bonds exist in the DNA nucleotide to ensure that different strands are connected to each other. These strands are composed of bonds between deoxyribose sugar and phosphate groups.
