ribosomiin
Ribosomiin, commonly known as the ribosome, is the universal molecular machine of protein synthesis in cells. It translates information encoded in messenger RNA into polypeptide chains, assembling amino acids in the order specified by the genetic code. The ribosome is a ribonucleoprotein complex composed of ribosomal RNA (rRNA) and ribosomal proteins, divided into a small subunit that reads the mRNA and a large subunit that catalyzes peptide bond formation.
In bacteria the subunits are 30S and 50S, forming a 70S ribosome; in eukaryotes the equivalents are
Biogenesis occurs in the nucleolus in most eukaryotes, where rRNA genes are transcribed and assembly begins
Ribosomes are targets for antibiotics that disrupt bacterial subunits without affecting eukaryotic ribosomes. Defects in ribosome
