Question

where are proteins made in the cell?
nucleus
ribosomes
cytoplasm
cell membrane

Explanation:

Ribosomes are the cellular structures responsible for protein synthesis. The nucleus contains DNA and is involved in genetic information storage and transcription but not protein - making. The cytoplasm is the fluid part of the cell where many organelles are suspended, but it is not the site of protein synthesis. The cell membrane is involved in cell - to - cell communication, transport, and protection, not protein production.

Answer:

ribosomes
