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 ...

The duration of expression of the gene Cdx2 is tightly regulated by a newly identified DNA sequence element called an “attenuator.” ...

Only recently has the ribosome -- one of the oldest molecular machines in evolutionary terms -- been recognized as an active regulator of gene expression at the level of protein biosynthesis.
