Ribosomes are composed of two subunits, the small and large subunits, each containing specific rRNA molecules. The main types of rRNA include: Small Subunit rRNA: In prokaryotes, the small subunit ...

When eukaryotic ribosomes are isolated from cell extracts, two different fractions are obtained, representing two subunits. The smaller 40S subunit binds the messenger RNA that constitutes the protein ...

Ribosomes are the sites in a cell in which protein synthesis takes place. Cells have many ribosomes, and the exact number depends on how active a particular cell is in synthesizing proteins.

Study findings reveal that P-stalk ribosomes (PSRs ... (to evaluate expression levels of specific immunoproteasome subunits) was used. Sucrose density gradient centrifugation identified and ...

by determining the first complete structures of both eukaryotic ribosomal subunits each in complex with an initiation factor. Recently, his group also obtained a breakthrough in visualizing mammalian ...

Differences in the ribosomal densities of the two daughters produced by a mother Escherichia coli could explain the asymmetry of aging and growth rate in previously reported such daughter pairs.

Within the ribosome, the mRNA and aminoacyl-tRNA complexes are held together closely, which facilitates base-pairing. The rRNA catalyzes the attachment of each new amino acid to the growing chain.

Their study demonstrates cancer cells may use our very own protein factories, ribosomes, to hide their visibility. The findings are published in Cell in an article titled, “P-stalk ribosomes act ...
