Here's a breakdown:
* Ribosomes are tiny, complex structures found in all living cells.
* They are the sites of protein synthesis, meaning they read the genetic code from messenger RNA (mRNA) and use that information to assemble amino acids into proteins.
* Ribosomes can be found free-floating in the cytoplasm or attached to the endoplasmic reticulum (ER).
