The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. The three-dimensional shape of a ...

An intriguing possibility presented by the authors is that this residue might play an important role in either the GTPase or GAP activities of the protein. Indeed SRP RNA may be required for ...

Overview of RNA repair – There is an emerging appreciation of the existence of “RNA repair” pathways that rely on RNA ligases to maintain or manipulate RNA structure in response to purposeful RNA ...

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 ...

This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA).
