Therefore, the transcriptome functions as a kind of catalog of all of the genes that are being expressed in a cell at a particular point in time. Ribosomes are the sites in a cell in which protein ...

Ribosomes are themselves composed of a complex ... or carry out one of many other important cellular support functions.

Only recently has the ribosome—one of the oldest molecular machines in evolutionary terms—been recognized as an active ...

Cell structure Description Function Cell type Cell wall Freely ... Fluid enclosed by the cell membrane, containing organelles and ribosomes Location of many chemical reactions All cell types ...

Ribosomal RNA is often modified with chemical tags that can alter the shape and function of the ribosome. Cells use these tags to fine tune protein production. The study found that, in response to ...

The research field of 'cellular IRESes' lay dormant for decades, as there was no uniform standard of reliable methods for the clear characterization of these starting points for the ribosome-mediated ...

Ribosomes are the cell’s molecular machines ... The scientists don’t know the CAT tails' function yet, but they have some ideas. They have evidence that suggests that CAT tails may trigger a stress ...

The rRNA molecules fold into complex secondary and tertiary structures, forming domains and motifs that are essential for ribosome function. The rRNA structures also provide binding sites for ...

During translation, multiple ribosomes travel along the nucleic acid chain to build polypeptides that become functional proteins. Occasionally, these molecular decoders pause on the mRNA, either ...

“Our study provides the first evidence that a male germ cell-specific Ribosome ST performed a different function, and were not replaceable by the core ribosome,” Guo says, adding that it was exciting ...

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.
