NEET (UG) 2024 — Question 122
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:
- Option A:
A and B only
- Option B:
D and E only
- Option C:Correct
B and C only
- Option D:
A and E only
Answer: C
Step-by-step solution
A piece of DNA carrying only the gene of interest, when transferred into an alien organism, is called recombinant DNA. Such a piece of DNA cannot replicate independently in the progeny cells because it lacks an origin of replication. It may get integrated into the genome of the recipient organism. Once integrated, it may multiply and be inherited along with the host DNA. Therefore, the correct statements are B and C, so the answer is option C.
