Question

Where does the actual formation of a protein (protein synthesis) occur within the cell?

1) Nucleus
2) Cytoplasm
3) Mitochondria
4) Endoplasmic reticulum

Answer 1

Protein synthesis occurs in the cytoplasm of the cell, specifically in the ribosomes. The ribosomes receive instructions from the nucleus through mRNA to create proteins.

Step-by-step explanation:

Ribosomes, the cellular structures responsible for protein synthesis, are located in the cytoplasm of the cell. They can be attached to the cytoplasmic side of the plasma membrane or the cytoplasmic side of the endoplasmic reticulum and the outer membrane of the nuclear envelope.

During protein synthesis, ribosomes receive instructions in the form of messenger RNA (mRNA) from the nucleus. The mRNA carries the genetic code transcribed from DNA, and the ribosomes translate this code into a specific sequence of amino acids to form a protein.
