Final answer:
DNA is the genetic blueprint of life, comprising four nucleotide bases that pair up in a complementary manner to form the DNA structure.
Explanation:
DNA (deoxyribonucleic acid) is the genetic blueprint of the cell, existing as a double-stranded nucleic acid polymer that carries hereditary information. It consists of four nucleotide bases: adenine (A), thymine (T), guanine (G), and cytosine (C). These bases pair up in a complementary manner - A with T and G with C - forming the building blocks of DNA.
