Question:
In genetic engineering, the foreign DNA is also called ___________ .
In genetic engineering, the foreign DNA is also called ___________ .
Show Hint
The foreign DNA to be cloned is called passenger DNA.
Updated On: Nov 13, 2026
vector DNA
cDNA
passenger DNA
r-DNA
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept
In genetic engineering a vector carries a gene of interest into a host.
Step 2: Terms
The foreign DNA is called passenger DNA (insert DNA), while the carrier is vector DNA.
Step 3: Compare the options
cDNA and r-DNA are different terms, with r-DNA being the combined molecule.
Final Answer:
Foreign DNA is called passenger DNA. \[ \boxed{\text{(C) }\text{passenger DNA}} \]
