The impact of the Human Genome Project on cancer research
Human Genome Project The Human Genome Project, which operated from 1990 to 2003, provided researchers with basic information about the genetic content of the human organism, opening new avenues of discovery in fields such as cancer research.

The Human Genome Project successfully sequenced approximately three billion chemical base pairs that constitute human genomic DNA.1

These base pairs consist of the four chemical building blocks: adenine (A), thymine (T), guanine (G), and cytosine (C).1
