Question

What is the fate of a piece of DNA carrying only gene of interest which is transfered in to 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 multiple and be inherited along with the host DNA.
D. The alien piece of DNA is not an integral part of chromasame.
E. It shows ability to replicate.
Choose the correct answer from the options given below:

• A. A and B only
• B. D and E only
• C. B and C only
• D. A and E only

Answer 1

Answer: (C)

B and C only

Answer 2

When a piece of DNA carrying a gene of interest is transferred into an alien organism, it may integrate into the recipient’s genome. This process ensures that the new genetic material is passed on to progeny cells. Alternatively, the DNA may replicate independently, but the key factor for long-term inheritance is its integration into the host’s genetic material.
