Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of molecular markers.
Step 2: Detailed Explanation:
RAPD (Random Amplified Polymorphic DNA) uses arbitrary primers (10-mer).
It samples the genome randomly and genome-wide.
It does not require prior sequence knowledge.
CAPS (A): Cleaved Amplified Polymorphic Sequences (PCR-based, targeted).
SNP (B): Single Nucleotide Polymorphism (specific loci).
SSR (D): Simple Sequence Repeats (microsatellites, specific loci).
Thus, RAPD is the marker that samples genome randomly and genome-wide.
Step 3: Final Answer:
Thus, RAPD samples genome randomly and genome-wide, which corresponds to option (C).

- 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" ?
