Join the Amoeba Sisters as they discuss gene expression and regulation in prokaryotes and eukaryotes. This video defines gene expression and explains how gene expression relates to gene regulation ...

Epigenetics, the dynamic regulation of genetic expression, involves complex molecular mechanisms. While the process of gene silencing by methylating the H3K27 position in histones is understood, not ...

In biology classrooms, we often learn that genes are transcribed into mRNA, which is then translated into proteins—a tidy, linear process. But gene expression in living cells is far more intricate, ...
