Question

How many copies (approximately) of DNA polymerase III are present in a typical bacterial cell?

(a) 10

(b) 50

(c) 100

(d) 200

I got this question by my school teacher while I was bunking the class.

This interesting question is from DNA Replication topic in portion DNA Replication and Repair, Cellular Reproduction of Cell Biology

Answer 1

The correct answer is:

(b) 50

Explanation:

In a typical bacterial cell, there are approximately 50 copies of DNA polymerase III. DNA polymerase III is the primary enzyme responsible for DNA replication in bacteria, and it functions as a complex of multiple subunits. Its concentration can vary depending on the phase of the cell cycle, but around 50 copies is a commonly accepted estimate for most bacterial cells during active replication.

Correct Answer: (b) 50
