Here's why:
* Protein Synthesis: Ribosomes are the sites of protein synthesis. They read the genetic code carried by messenger RNA (mRNA) and use that information to link amino acids together in the correct order, creating polypeptide chains that fold into functional proteins.
* Other Substances: While primarily known for protein synthesis, ribosomes can also produce other substances, such as:
* RNA molecules: Ribosomes are involved in the production of ribosomal RNA (rRNA) and transfer RNA (tRNA), which are essential components of the protein synthesis machinery.
* Peptides: Some ribosomes produce short chains of amino acids called peptides, which can have various functions in the cell.
