Question

Nucleotides are made up of

Answer 1

Nucleotide:

1. A nucleotide is the basic building block of nucleic acids (RNA and DNA).
2. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.
3. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
4. In RNA, the base uracil (U) takes the place of thymine.
5. DNA and RNA molecules are polymers made up of long chains of nucleotides.

Final answer: Nucleotides are made up of sugar molecules, a nitrogen-containing base, and a phosphate group.
