Question:
The vector that could be used in two different systems/hosts are called
The vector that could be used in two different systems/hosts are called
Show Hint
Shuttle vectors:
- Replicate in two different hosts.
- Examples: pYES (E. coli and yeast), pBI (E. coli and Agrobacterium).
- Allow transfer of genes between organisms.

Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of cloning vectors.
Step 2: Detailed Explanation:
Shuttle vectors can be used in two different hosts/systems.
They have origins of replication for both hosts (e.g., E. coli and yeast).
Cosmids (A): Hybrid of plasmid and phage lambda cos sites.
Phagemids (B): Hybrid of phage and plasmid.
Plasmids (D): Small circular DNA, used in bacteria.
Thus, shuttle vectors are used in two different systems.
Step 3: Final Answer:
Thus, shuttle vectors are used in two different systems, 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" ?
