Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of virology terminology.
Step 2: Detailed Explanation:
Bacteriophages (phages) are viruses that infect bacteria.
They are used in molecular biology (e.g., phage display, transduction).
Cosmids (A): Hybrid vectors (plasmid + phage cos sites).
Plasmids (B): Circular DNA molecules (not viruses).
Mycoplasma (D): Cell-wall-lacking bacteria (not viruses).
Thus, bacteriophages infect bacteria.
Step 3: Final Answer:
Thus, bacteriophages are viruses that infect bacteria, which corresponds to option (C).

- Which of the following molecules can be classified under glycosphingolipid category?
- The bicarbonate buffer is a principal buffering system in blood plasma. The ratio of the bicarbonate to carbonic acid required to maintain pH of plasma at 7.4 is:
- 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" ?
- Match List-I with List-II
List-I (Name of the Enzyme) & List-II (Class of the enzyme)
(A). Pyruvate carboxylase & (I). Oxidoreductase
(B). Fumarase & (II). Hydrolase
(C). Phospholipase & (III). Lyase
(D). Nitrogenase & (IV). Ligase
