Which of the following best describes the structure of a nucleotide?

Question

Question 1 options:

a pair of 6 carbon rings attached to each other

a chain of carbon and nitrogen atoms with a variable group

a five-carbon sugar attached to a phosphate group and to a nitrogenous base

a carbon atom joined to hydrogen and three fatty acids

Answer 1

The option that best describes the structure of a nucleotide is:

a five-carbon sugar attached to a phosphate group and to a nitrogenous base

Nucleotides consist of three main components: a five-carbon sugar (ribose in RNA or deoxyribose in DNA), a phosphate group, and a nitrogenous base (which can be adenine, guanine, cytosine, thymine, or uracil).
