What is the structure and function of ribosomes?

In specifics: Ribosomes function as the cell's construction workers, interpreting an mRNA sequence, translating it, and using tools to assemble it into a protein that the cell can use.

The rRNA and different proteins that make up ribosomes allow them to function as free-floating organelles in the cytoplasm or as structures that can be attached to the endoplasmic reticulum (ER) to carry out specific functions associated with it.

Located in the cytoplasm and attached to the endoplasmic reticulum in eukaryotic cells, ribosomes are cellular organelles that are responsible for protein synthesis. They are structurally composed of two subunits, ribosomal RNA (rRNA) and proteins. Ribosomes read messenger RNA (mRNA) and use the information to assemble amino acids into polypeptide chains during translation, which eventually fold into functional proteins.
