Worms decipher a bacterial code to drive multigenerational change in behavior

Review written by Olivia Duddy (MOL)

Segments of DNA, called genes, encode the expression of an organism’s traits. Genes are heritable, meaning that they are transmitted from the parent to their progeny. Additionally, scientists have uncovered mechanisms that enable changes in gene function, independent of changes in DNA sequence, that are also heritable. The study of these mechanisms, collectively known as epigenetics, has revealed ways in which the environment shapes our biology in the context of health and disease.
