If our genes are so similar, what really makes a eukaryote different from a prokaryote, or a human from E. coli? The answer lies in the difference in gene expression and regulation used. Regulation of ...

Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of ...

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 ...

Gene expression, the intricate process by which cells selectively activate genes to produce proteins, is crucial for cellular ...

Origin-recognition complex, or ORC, plays an unexpectedly broad role in the regulation of human cell gene expression, according to a study in the journal Cell Reports. This is the first detailed study ...
