Question:
Ribosomes are essential for the synthesis of which of the following?
Ribosomes are essential for the synthesis of which of the following?
Show Hint
Ribosomes are often referred to as the "protein factories" of the cell.
This fundamental nickname makes it very straightforward to associate them directly with protein synthesis.

The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Ribosomes are specialized cellular organelles present in both prokaryotic and eukaryotic cells that serve as the primary site for translation.
Step 3: Detailed Explanation:
1. Ribosomes are composed of ribosomal RNA (rRNA) and proteins.
2. During gene expression, the genetic code transcribed into messenger RNA (mRNA) is read by the ribosomes.
3. Transfer RNA (tRNA) molecules bring the appropriate amino acids to the ribosome, which links them together via peptide bonds to synthesize polypeptides (proteins).
4. Therefore, ribosomes are uniquely and critically essential for protein synthesis.
Step 4: Final Answer
The correct option is (B).
