Cell function is determined by how DNA is expressed into proteins. That process includes two main steps—transcription, when ...

While scientists have known for more than two decades that all cells use a strategy called RNA interference to regulate gene expression, a new study is the first to describe how a specific protein ...

WEST LAFAYETTE, Ind. — Researchers interested in improving a given trait in plants can now identify the genes that regulate the trait’s expression without doing any experiments. The Purdue-USDA team ...

The correct functioning of cells relies heavily on the ability to finely control gene expression, a complex process by which the information contained in DNA is copied into RNA to eventually give rise ...

Epigenetics is the study of various heritable alterations that control gene expression without changing the DNA sequence. 1 The name epigenetics comes from the Greek prefix “epi”, which means on top ...
