Similar to the way the caps on the ends of a shoelace prevent it from fraying, telomeres—regions of repetitive DNA sequences ...

“Think of DNA as an instruction manual,” Worthey said. “It tells our cells how to form, operate, and interact with their surroundings.” Most DNA is stored in the cell nucleus. A small portion is found ...

DNA and RNA methylation, initially thought to operate as distinct pathways, have been shown to interact closely, shifting our understanding of gene regulation. A team of researchers from the ...

RNA in control By uncovering RNA’s previously unknown function to repair DNA damage, our findings show how RNA may directly contribute to the stability and evolution of the genome.

Until now, DNA and RNA epigenetics were studied as independent systems. These two mechanisms seemed to function separately, each playing its own role in distinct stages of the gene regulation process.

Banerjee is also exploring RNA’s role in the origin of life, thanks to a seed grant from the Hypothesis Fund. He is studying whether biomolecular condensates may have protected RNA’s functions as ...

NASA's OSIRIS-REx mission found ingredients for DNA and RNA on the asteroid Bennu. The discovery shows asteroids could seed planets with the precursors for life. It's also more evidence that life ...
