Scientists have finally captured footage of the microscopic machinery that allows our cells to copy DNA—a fundamental process ...

In a hair follicle cell, a protein called keratin is made. Lots of it. Many ribosomes can be working on a single strand of mRNA at once. Protein synthesis isn't a slow process, either. A protein ...

RNA molecules differ from DNA molecules in several important ways: They are single stranded rather than double ... of transcripts encoding structural proteins. Other mRNAs are quite rare, with ...

Boosting cells with a tardigrade protein reduced DNA damage after radiation, offering potential protection for healthy tissue ...

The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer.

In eukaryotic cells, single-stranded DNA (ssDNA) becomes rapidly coated with the protein RPA (replication protein A). RPA has a higher affinity for ssDNA than Rad51, and it therefore can inhibit ...

A new structural blueprint paves the way for improved targeting of cancer cells, particularly those with BRCA1 and BRCA2 ...

The newly formed strand of mRNA is now ready to leave the nucleus and travel to the ribosome. After translation, the polypeptide is finally folded into the correct shape and becomes a protein.

In the work, the researchers added the vitamin biotin to those short DNA strands to turn the system into a sensor for the protein streptavidin. Then they added a DNA aptamer, a DNA strand that can ...

Researchers uncover new insights into the molecular mechanisms of ADAR1, a protein that regulates RNA-induced immune responses. Their findings could open new pathways for treating autoimmune diseases ...
