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.

HHMI scientists and their colleagues discover a new mechanism of protein synthesis. Ribosomes are the cell’s molecular machines, responsible for translating genetic information in messenger RNA into ...

The ribosome is a large assembly of proteins and ribosomal RNAs (rRNAs) that functions to translate messenger RNAs (mRNAs) into proteins. The ribosome catalyzes the assembly of amino acids into ...

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 ...

We find that these inhibitors slow elongating ribosomes, thereby inducing a queue of pre-initiation complexes that can become positioned over and initiate from an otherwise poorly recognized start ...
