Researchers at Utah State University have reported a previously unrecognised CRISPR immune response in which a bacterial ...

Across all domains of life, immune defenses foil invading viruses by making it impossible for the viruses to replicate. Most ...

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

The new findings strengthen the "RNA world" hypothesis that describes how the first life on Earth could have used RNA instead ...

tRNAs have a distinct cloverleaf secondary structure and an L-shaped tertiary structure. The cloverleaf structure is formed by the folding of the single-stranded tRNA molecule, which is typically ...
