Question

Many ribosomes may associate with a single mRNA to form multiple copies of a polypeptide simultaneously. such strings of ribosomes are termed?

• A. Polyhedral bodies
• B. Plastidome
• C. Nucleosome
• D. Polysome

Answer 1

The correct option is D

Polysome

The correct option is D.

Explanation for the correct option:

1. Polysomes are knowns as single mRNA which is translated by many ribosomes.
2. It results in the synthesis of multiple copies of a polypeptide.
3. Polysomes are also known as polyribosomes or ergosomes.

Explanation for the incorrect options:

Option A:

Polyhedral bodies are inclusion bodies that are associated with the replication of certain insect viruses.

Option B:

All the plastids of cells collectively are called plastidome.

Option C:

The nucleosome is the basic unit consisting of DNA wrapped around four histone proteins.

Final answer: Many ribosomes may associate with a single mRNA to form multiple copies of a polypeptide simultaneously. such strings of ribosomes are termed Polysomes.
