Question:

Read the passage and answer the following questions :
Translation refers to the process of polymerisation of amino acids to form a polypeptide. The order and sequence of amino acids are defined by the sequence of bases in the mRNA. The amino acids are joined by a bond which is known as a peptide bond. Formation of a peptide bond requires energy.

Which among the following is the site of protein synthesis ?

Options:

Mitochondria

Golgi bodies

Ribosomes

Lysosomes

Correct Answer:

Ribosomes

Explanation:

The correct answer is Option (3) - Ribosomes

The site of protein synthesis in a cell is primarily the ribosomes.

Ribosomes are the cellular organelles responsible for the synthesis of proteins. They can be found either free in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes read the genetic information encoded in messenger RNA (mRNA) and facilitate the assembly of amino acids into a specific sequence, forming proteins based on the instructions provided by the mRNA. While mitochondria, Golgi bodies, and lysosomes are essential cellular organelles with various other functions.

Therefore, The specific organelle responsible for protein synthesis is the ribosome.
