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 ...

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, ...

All the cells in an organism have the exact same genetic sequence. What differs across cell types is their epigenetics—meticulously placed chemical tags that influence which genes are expressed in ...

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 ...

In a significant breakthrough for biology and medical research, Indian scientists have uncovered new insights into how ...

Aging may "erase" the epigenetic markers that control gene expression in the brain, and this may snowball to cause unintended ...

Researchers have mapped how "histone bivalency" acts as a molecular clock for brain development. By holding genes in a poised state, this mechanism ensures neurons mature only after completing ...

An important DNA modification is methylation, or the addition of a methyl group to the 5th carbon of cytosine. This forms 5-methylcytosine (5mC), typically associated with repression of gene ...

Researchers discover a protein that connects GLP-1 drugs to long-term, broad genomic responses that can promote pancreatic ...
