ribosome (n)
an organelle in the cytoplasm of a living cell; they attach to mRNA and move down it one codon at a time and then stop until tRNA brings the required amino acid; when it reaches a stop codon it falls apart and releases the completed protein molecule for use by the cell

ribosome Sentence Examples
- Ribosomes are the cellular machinery responsible for protein synthesis.
- Ribosomes are composed of two subunits, a large subunit and a small subunit.
- Ribosomes attach to messenger RNA (mRNA) and read the genetic code to assemble amino acids into a polypeptide chain.
- Each ribosome has three binding sites: the A site, the P site, and the E site.
- The A site binds the incoming aminoacyl-tRNA, the P site holds the tRNA with the growing polypeptide, and the E site releases the spent tRNA.
- The movement of the ribosome along the mRNA is called translocation.
- Ribosomes are found in both prokaryotes and eukaryotes.
- In prokaryotes, ribosomes are free in the cytoplasm, while in eukaryotes, they are bound to the endoplasmic reticulum or are present in mitochondria and chloroplasts.
- Antibiotic drugs can target ribosomes and inhibit protein synthesis.
- Defects in ribosomal function can lead to genetic diseases.
