Question:
Vehicle DNA in rDNA technology is the common name given to __________
Vehicle DNA in rDNA technology is the common name given to __________
Show Hint
The DNA that carries the foreign gene into the host cell is called a vehicle.
Updated On: Nov 13, 2026
- r-DNA
- Cloning vector
- c-DNA
- Passenger DNA
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
In recombinant DNA technology, a foreign gene is inserted into a carrier DNA molecule which transports it into the host cell.
Step 2: Identify the Vehicle
This carrier is also called a vector, for example a plasmid or a bacteriophage.
Because it is used for cloning the gene, it is called a cloning vector.
Step 3: Compare the options
The foreign gene is the passenger DNA, so option D is not the vehicle.
r-DNA is the recombinant molecule and c-DNA is DNA copied from mRNA.
Final Answer:
Vehicle DNA is known as the cloning vector. \[ \boxed{\text{(B) }\text{Cloning vector}} \]
