epigenomics, the study of chemical changes that regulate the expression, or use, of the entire collection of DNA molecules in an organism’s cells. This collection of genetic material is known as the organism’s genome. Genomes serve as dynamic blueprints, directly or indirectly enabling the synthesis of all the macromolecules needed for life. Epigenomics is the study of the regulated expression of those blueprints. More precisely, it is the study of how, when, where, and why cells decorate specific regions of their DNA in sometimes heritable and sometimes temporary ways in order to activate or silence the expression of specific genes. ...(100 of 938 words)
