Question: 96. What is the fate of a piece of DNA carrying only gene of interest which is transferred into an alien organism?
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
Answer: Option (3)
Explanation:
When a piece of DNA carrying only the gene of interest is transferred into an alien organism,
it cannot replicate independently on its own.
For stable maintenance, the transferred DNA may integrate into the genome of the recipient organism.
Once integrated, it replicates along with the host DNA during cell division.
As a result, the gene of interest is inherited by the progeny cells together with the host genome.
Therefore, statements B and C correctly describe the fate of such transferred DNA.
