Epigenetics refers to alterations in gene expression that cannot be explained by changes in the sequence of deoxyribonucleic acid. Epigenetic traits have significant economic and medical relevance. For example, during the last few years it has become...

Epigenetics is a term in biology used today to refer to features such as chromatin and DNA modifications that are stable over rounds of cell division but do not involve changes in the underlying DNA sequence of the organism.[1] These epigenetic changes...

Chromosomes and genes make up only half of our DNA. The other half consists of the epigenome, protein molecules along the length of the double helix. These molecules control how, when, and where a gene is expressed. In a sense, the genes provide...

Genetics and genomics must share an ever-widening spotlight The genetic model of cancer-the idea that key mutations lead to unchecked cellular proliferation-has guided cancer research for decades. Thousands of papers report sequence alterations that disrupt, delete, or overexpress genes, leading to oncogenesis. Then,...
