Answer 2

Nucleotides are linked to make up DNA

Explanation:

DNA is also called deoxyribose nucleic acid, it is the cause of heredity in our body. DNA is formed by certain molecules which are known as nucleotides. The nucleotide is further divided into a phosphate group, a base that is made of nitrogen and sugar.

Nitrogen bases are namely adenine, guanine, thymine and cytosine. It is a double-stranded helix structure. The double-stranded DNA structure consists of two polynucleotides which are arranged with nitrogen bases.
