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.

"Ribosomes are very large macromolecular machines that very rapidly and precisely decode mRNA into protein. For a long time, they've been viewed as kind of 'dumb code-reading machines' that don't ...

A previously unknown kind of ribosome is responsible for folding sperm proteins, which decay before fertilization if prepared by other ribosomes. Dan is a News Editor at The Scientist. He writes and ...

Ribosomes turn upside-down in hungry cells Scientists have observed that yeast cells have a remarkable adaptation to ...

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 ...

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 ...

Messenger RNA carries genetic information from DNA in the highly protected nucleus out to the rest of the cell, where structures called ribosomes can build proteins according to the DNA blueprint.

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.
