DNA Chemistry and Sex Chromosomes

An elegant visual introduction to the chemistry of DNA and the fundamentals of biological sex determination; DNA Chemistry and Sex Chromosomes presents the iconic double helix in a clean, modern format that makes molecular biology immediately accessible. The artwork highlights the four nitrogenous bases — Guanine, Cytosine, Thymine and Adenine — and clearly illustrates their complementary pairing (G–C and A–T), reinforcing the structural logic that underpins genetic coding.
