RNA’s Surprising Role in DNA Repair New insights could lead to improved treatments for cancer and other diseases. Francesca Storici and her research team discovered a surprising role for RNA in DNA ...

Our genes contain all the instructions our body needs to function, but their expression must be finely regulated to guarantee that each cell performs its role optimally. This is where DNA and RNA ...

Nucleic acids are complex biological molecules that store and transmit genetic information in all living organisms. They are essential for the survival and reproduction of life on Earth. The two main ...

Your DNA is continually damaged by sources both inside and outside your body. One especially severe form of damage called a double-strand break involves the severing of both strands of the DNA double ...

Ribonucleic acid, also called RNA, is a molecule present in all living cells. It plays a critical role in transmitting genetic instructions from DNA and creating proteins. With the power to execute a ...

A new study has discovered an unprecedented pathway producing telomerase RNA from a protein-coding messenger RNA (mRNA). For the very first time, a study led by Julian Chen and his group in Arizona ...

RNA transcription is the genomic process in which a cell produces a duplicate of a gene's DNA sequence. In a study published in Nucleic Acids Research, University of Alabama at Birmingham Department ...
