What to know about Life speaks one universal language to activate genes: It speaks many more to silence them

Researchers from the Center for Genomic Regulation have published a study in Nature Genetics showing that while gene activation mechanisms are consistent across eukaryotes, gene silencing mechanisms vary significantly across different branches of life. The study utilized a new method called iChIP2 to analyze chromatin across diverse species, suggesting that these differences evolved as a response to parasitic DNA elements.

What happened

Life speaks one universal language to activate genes: It speaks many more to silence them Sadie Harley Scientific Editor Robert Egan Senior Editor The signals that cells use to switch genes on have remained almost unchanged across 2 billion years of…

Why it matters

The findings, published in Nature Genetics, are the result of the broadest comparative analysis to date of how different life forms regulate their genomes.

Common ground

The study carried out the first detailed analysis of chromatin, the protein scaffold that controls how DNA is read, in several major branches of life that have been largely absent from studies to date, including lineages such as discobans, rhizarians,…
