Question:
The DNA replication in prokaryotes is of
The DNA replication in prokaryotes is of
Show Hint
Semi-conservative replication:
- Each daughter molecule has one old and one new strand.
- Meselson-Stahl experiment proved semi-conservative replication.
- Conservative replication: Old strands remain together.
- Each daughter molecule has one old and one new strand.
- Meselson-Stahl experiment proved semi-conservative replication.
- Conservative replication: Old strands remain together.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of DNA replication mechanisms.
Step 2: Detailed Explanation:
DNA replication in prokaryotes is semi-conservative.
Each parental strand serves as a template for a new strand.
Each daughter molecule contains one old and one new strand.
This was demonstrated by the Meselson-Stahl experiment.
Conservative (B): Parental strands remain together.
Disruptive (C): Not a standard term.
Semi-disruptive (D): Not a standard term.
Thus, prokaryotic DNA replication is semi-conservative.
Step 3: Final Answer:
Thus, DNA replication in prokaryotes is semi-conservative, which corresponds to option (A).

- Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A): The disruption of $\beta$-oxidation of fatty acids in plants can potentially reduce stress-induced ROS accumulation and improve its stress tolerance.
Reason (R): In plants, $\beta$-oxidation of fatty acids takes place predominantly in peroxisomes, where first enzyme of $\beta$-oxidation viz. fatty acyl CoA oxidase produces large amounts of hydrogen peroxide.
In light of the above statements, choose the correct answer from the options given below. - The serum level of which of the following metabolites can effectively distinguish "Vitamin B12 deficiency" from "Folate deficiency" ?
