A 2-gram chunk from this rock — a piece of the meteorite that fell near Murchison, Australia, in 1969 — contains two crucial components of DNA and RNA now identified for the first time in an ...

The process of making a ribonucleic acid (RNA) copy of a DNA (deoxyribonucleic acid) molecule, called transcription, is necessary for all forms of life. The mechanisms involved in transcription ...

A deeper understanding of RNA’s role in DNA repair could lead to new strategies for strengthening repair mechanisms in healthy cells, potentially reducing the harmful effects of treatments like ...

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.

Like DNA, it can form double strands with itself, as well as with DNA or RNA, making it a promising genetic system (Science, DOI: 10.1126/science.1174577).

Small Cajal body-associated RNA 2 (scaRNA2) regulates DNA repair pathway choice by inhibiting DNA-PK. Nature Communications, 2022; 13 (1) DOI: 10.1038/s41467-022-28646-5 ...
