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 ...

Roberts in 1958. Subsequent studies by James Watson, Francis Crick, and others revealed the central role of ribosomes in protein synthesis, laying the foundation for our current understanding of these ...

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.

The large subunit rRNA, in particular, is responsible for the peptidyl transferase reaction, which catalyzes the formation of peptide bonds between amino acids during protein synthesis. This discovery ...

acting out the various macromolecules involved in protein synthesis. Two groups form the subunits of the ribosome, a chain of ballon-headed students act as the messenger RNA (mRNA) that codes for ...

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 chain 400 amino acids long can be assembled in 20 seconds!

“Over 40 percent of the clinically useful antibiotics target protein synthesis, mostly by paralyzing the ribosome,” she notes. But her interactions with pharmaceutical companies about new ...
