By using the enzyme DNA ligase, foreign DNA is integrated into the vector. The combination of vector DNA and foreign DNA is called
By using the enzyme DNA ligase, foreign DNA is integrated into the vector. The combination of vector DNA and foreign DNA is called
Show Hint
DNA ligase joins two DNAs of different origin. The product has more than one accepted name.
Updated On: Nov 12, 2026
- Complementary DNA
- Recombinant DNA
- Chimeric DNA
- Recombinant DNA as well as Chimeric DNA.
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
DNA ligase seals the foreign DNA into the cut vector by forming phosphodiester bonds.
Step 2: Name of the product
DNA from two sources joined together is called recombinant DNA, also termed chimeric DNA.
Step 3: Rule out cDNA
Complementary DNA is DNA made from mRNA by reverse transcriptase, so it does not fit.
Final Answer:
The product is both recombinant DNA and chimeric DNA. \[ \boxed{\text{(D) }\text{Recombinant DNA as well as Chimeric DNA.}} \]
