Without altering the genetic code in the DNA, epigenetic modifications can change how genes are expressed, affecting an organism's health and development. The once radical idea that such changes in gene expression can be ...

Natural selection has produced mammals that age at dramatically different rates. Take, for example, naked mole rats and mice; the former can live up to 41 years, nearly ten times as long as similar-size rodents such as mice.

In most mammals, females have two X chromosomes and males have one X and one Y chromosome in each of their cells. To avoid a double dose of X-linked genes in females, one of the Xs is silenced early in the developmental process. ...

Cells use RNA as a versatile tool to regulate the activity of their genes. Small snippets of RNA can fine-tune how much protein is produced from various genes; some small RNAs can shut genes off altogether. An enzyme called ...
