Site of protein synthesis in cell is:

Correct answer: A. Ribosome

  • A. Ribosome
  • B. Endoplasmic reticulum
  • C. Nucleolus
  • D. Smooth endoplasmic reticulum

Explanation

The correct answer is Ribosome. Ribosomes are the cellular organelles where proteins are synthesized by translating messenger RNA (mRNA) into polypeptide chains. While the rough endoplasmic reticulum works closely with ribosomes in protein synthesis, it is not the primary site. The nucleolus, on the other hand, is responsible for making ribosomes, and the smooth endoplasmic reticulum is involved in lipid synthesis, not protein synthesis.
