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 E only

2. A and B only

3. D and E only

4. B and C only

Best answer

Answer: 4. B and C only

Key idea: a piece of alien DNA without an origin of replication cannot multiply on its own.

It either integrates into the host genome (B) and is then multiplied and inherited with the host DNA (C), or it is lost. Statements A and E claim independent replication, which needs an origin of replication, so they are wrong for DNA carrying only the gene of interest. D is not a consequence stated for this case.
