Final answer:
Ribosomes are cellular structures responsible for protein synthesis. They translate genetic information from mRNA into proteins.
Step-by-step explanation:
Ribosomes are cellular structures responsible for protein synthesis. They consist of large and small subunits and can be attached to the cytoplasmic side of the plasma membrane or the endoplasmic reticulum. Ribosomes translate the genetic information carried by messenger RNA (mRNA) into a specific order of amino acids in a protein.
