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 ...

Turning genes on and off is like flipping a light switch, controlling whether genes in a cell are active. When a gene is turned on, the production of proteins or other substances is promoted; when ...

MIT engineers designed a control mechanism, known as DIAL, that allows them to establish a desired protein level, or set point, for any synthetic gene circuit.

Most people recognize Alzheimer's from its devastating symptoms such as memory loss, while new drugs target pathological aspects of disease manifestations, such as plaques of amyloid proteins. Now a ...
