Question

Which of the following is the primary function of ribosomes in a cell?

• A. Protein synthesis
• B. Energy production
• C. DNA replication
• D. Transport of materials

Hint:

Ribosomes are essential for the synthesis of proteins in cells. They can be free in the cytoplasm or bound to the endoplasmic reticulum.

Answer 1

The Correct Option is A

Ribosomes are the molecular machines in the cell responsible for protein synthesis. They read the mRNA and translate it into a specific sequence of amino acids, forming a polypeptide chain.
- Option (1) is correct: Ribosomes are involved in the synthesis of proteins.
- Option (2) refers to mitochondria, which are responsible for energy production in the form of ATP.
- Option (3) refers to the nucleus, where DNA replication occurs.
- Option (4) refers to the endoplasmic reticulum and Golgi apparatus, which are involved in the transport of materials.
Thus, the primary function of ribosomes is protein synthesis.
