Explanation:
DNA molecule is made up of only four types of nucleotides that are adenine, guanine, cytosine, and thymine.

The four nucleotides are arranged in the DNA strand with many different combinations which results in the formation of codons sequence that contains all the information about the cell. This long DNA is compressed several times to fit in the nucleus.
