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 ...

Learn more about the DNA and RNA that sperm carry and how they may suddenly change during midlife.

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 ...

Researchers from Carnegie Mellon University have discovered a way to target RNA that could lead to new treatment options for ...

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 ...

Researchers say discoveries could expand the CRISPR toolbox and lead to more efficient, rapid diagnostic tools for detecting COVID-19, influenza, and RSV.

This image illustrates the chemical structure of a purine molecule, highlighting the numbering of the carbon and nitrogen atoms. The purine structure consists of a pyrimidine ring (positions 1 to 6) ...

Ancient DNA has been pulled from a permafrost-preserved woolly mammoth found in Siberia, and scientists are thrilled. They ...

Across all domains of life, immune defenses foil invading viruses by making it impossible for the viruses to replicate. Most known CRISPR systems target invading pathogens' DNA and chop it up to ...
