Answer 2

Nucleotides are the basic structural units of nucleic acids, such as DNA and RNA. They are composed of three main components:

1. **A nitrogenous base**: There are five primary nitrogenous bases found in nucleotides—adenine (A), guanine (G), cytosine (C), thymine (T) for DNA, and uracil (U) for RNA.

2. **A five-carbon sugar**: This sugar can either be deoxyribose (in DNA) or ribose (in RNA), distinguishing the two types of nucleic acids.

3. **One or more phosphate groups**: These phosphate groups are responsible for linking nucleotides together to form the backbone of nucleic acids through phosphodiester bonds.

In summary, nucleotides are the building blocks of nucleic acids and are composed of a nitrogenous base, a five-carbon sugar, and one or more phosphate groups.
