WebRibosomes are a large and complex molecular machine that catalyzes the synthesis of proteins, referred to as translation. The ribosome selects aminoacylated transfer RNAs (tRNAs) based on the sequence of a protein-encoding messenger RNA (mRNA) and covalently links the amino acids into a polypeptide chain. WebThey are located in the mitochondria, nucleolus, and chloroplasts, among other places. Ribosomes are tiny, averaging just about 25 nanometres in diameter. Free ribosomes are found free in the cytoplasm, while attached ribosomes are coupled to the outside of the endoplasmic reticulum or nuclear envelope to manufacture proteins.
