Q.

What is the fate of a piece of DNA carrying only gene of interest which is transferred into an alien organism      [2024]
A. The piece of DNA would be able to multiply itself independently in the progeny cells of the organism.
B. It may get integrated into the genome of the recipient.
C. It may multiply and be inherited along with the host DNA.
D. The alien piece of DNA is not an integral part of chromosome.
E. It shows ability to replicate.

Choose the correct answer from the options given below:
1 A and B only  
2 D and E only  
3 B and C only  
4 A and E only  

Ans.

(3)

A piece of DNA when introduced in organisms is not able to multiply itself and can multiply only when it gets integrated into the genetic material of the recipient organism. This is because the alien piece of DNA has become a part of the recipient chromosome.
