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 ...

It is a near sphere of protein (cross section shown) inside a fatty membrane that protects a twisting strand of RNA--a molecule that holds the virus's genetic code. Proteins called "S" form spikes ...

Only recently has the ribosome - one of the oldest molecular machines in evolutionary terms - been recognized as an active regulator of gene expression at the level of protein biosynthesis.

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

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 ...

the researchers saw a 50 percent reduction in the amount of double-stranded DNA breaks caused by radiation. The researchers also showed that the protective effect of the Dsup protein did not ...
