Researchers uncovered a previously unknown CRISPR immune response in bacteria that targets transfer RNAs. The newly ...

How does the cell convert DNA into working proteins? The process of translation can be seen as the decoding of instructions for making proteins, involving mRNA in transcription as well as tRNA. But ...

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 ...

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

Researchers at Utah State University revealed new details about CRISPR immune system defenses, such as Cas12a3 systems, that ...

A novel CRISPR defense mechanism, unlike known nucleases, specifically destroys transfer ribonucleic acids (tRNA) that are ...

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

New method uses DNA barcodes for high throughput RNA and protein detection in deep tissue. ScienceDaily. Retrieved January 7, 2026 from www.sciencedaily.com / releases / 2025 / 03 / 250311121315.htm ...

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 ...

A trio of mRNA molecules could help guard against the harmful effects of aging on immune cells, a study in mice finds. A new ...

Proteins are essential biological molecules that perform a vast array of functions crucial for life, from catalyzing ...
