Answer 1

In the cells of multicellular organisms, proteins are assembled in the ribosomes. Ribosomes can be found either free-floating in the cytoplasm or attached to the endoplasmic reticulum (ER), which is then referred to as rough ER. The ribosomes synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains, which then fold into functional proteins. The endoplasmic reticulum and other cellular structures, like the Golgi apparatus, are involved in the post-translational modifications and transport of these proteins.
