PY - 2021 T2 - The Basic Science of Oncology, 6e AB - The human genome found in each cell of the body consists of ~6 billion bases of DNA forming a sequence unique to each individual. This sequence contributes to differences in phenotypic traits among individuals, such as height, as well as risks of developing different diseases. However, the DNA sequence alone cannot account for the phenotypic identity that discriminates between different cell types and tissues of a human being, because (with few exceptions) the DNA sequence is largely identical in each cell. Thus, cell type–specific gene expression programs require an additional system of control to achieve this phenotypic diversity, a system commonly referred to as epigenetics.
