In “Counting DNA Nucleotides”, we described the primary structure of a nucleic acid as a polymer of nucleotide units, and we mentioned that the omnipresent nucleic acid DNA is composed of a varied sequence of four bases.

Counting DNA Nucleotides
Making up all living material, the cell is considered to be the building block of life. The nucleus, a component of most eukaryotic cells, was identified as the hub of cellular activity 150 years ago. Viewed under a light microscope, the nucleus appears only as a darker region of the cell, but as we increase magnification, we find that the nucleus is densely filled with a stew of macromolecules called chromatin. During mitosis (eukaryotic cell division), most of the chromatin condenses into long, thin strings called chromosomes.
