Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of gene expression patterns.
Step 2: Detailed Explanation:
Housekeeping genes are expressed all the time (constitutively).
They are required for maintaining basic cellular functions.
Examples: Actin, GAPDH, ribosomal proteins, ATP synthase.
Oncogenes (A): Genes that can cause cancer when mutated or overexpressed.
Progenes (B): Not a standard term.
Mutagenes (D): Not a standard term (mutagen means agent that causes mutation).
Thus, housekeeping genes are expressed continuously.
Step 3: Final Answer:
Thus, housekeeping genes express all the time, 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" ?
