Bettie J. Graham, Ph.D. defines Ribosome

Ribosome

RAHY buh sohm

A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.

Ribosome

A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.

Narration Transcription

Ribosomes are a part of the protein-generating factory in the cell. The ribosome itself is a two-subunit structure that binds to messenger RNA. And this structure acts as a docking station for the transfer RNA that contains the amino acid that will then become part of the growing polypeptide chain, which eventually becomes the protein.
