Smaller nucleoli slow aging, acting as a "mortality timer," while larger nucleoli lead to cell death by destabilizing rDNA. The secret to cellular youth may lie in maintaining a small nucleolus—a ...

With so many at-home DNA tests now available to consumers, learning more about your ancestry is easier than ever. Plus, these tests make for thoughtful, unique holiday gifts. All you have to do is ...

Different parts of the genome occur in different amounts and the regions with more copies of DNA (i.e., the full chloroplast genome and nuclear ribosomal DNA) drown out the weaker signals from the ...

At one time or another, most of us have played with a flipbook, using our thumbs to rapidly flip a series of pictures to create an illusion of movement. Scientists use a similar technique to study ...

RiboD-PETRI, a cost-effective, equipment-free plate-based scRNA-seq technique that integrates a unique bacterial rRNA depletion protocol, significantly enhancing mRNA detection rate and revealing ...

Recent years have seen considerable advances in the description and understanding of mitochondrial DNA (mtDNA) disorders. However, progress towards therapies and prenatal diagnosis of mtDNA ...

Dec. 20, 2024 — Combining bioinformatics and experimetal approaches, researchers have discovered replication hubs for human norovirus, the leading cause of viral gastroenteritis accounting for ...

Dec. 20, 2024 — Researchers have made a meaningful advance in the simulation of molecular electron transfer -- a fundamental process underpinning countless physical, ... Study Reveals Right ...

Ribosomes are made of proteins and a special type of RNA molecule called ribosomal RNA (rRNA). rRNA molecules are the target of chemical modifications, affecting the ribosome's function.

A growing concern is the bacterium’s resistance to clarithromycin, driven by mutations in the 23S ribosomal RNA gene, which ...
