Question

Conservative site-specific recombination can result in all of the following except?

-inversion of a DNA segment
-insertion of a DNA segment at a specific site
-deletion or removal of a DNA segment
-separation of interlocked circular DNAs

Answer 1

The correct option is Option D

i.e. Separation of interlocked circular DNAs.

Step-by-step explanation:

The site specific recombination of DNA is a process where either two DNA molecules exchange a small part of their DNAs with each other or a smaller part of DNA is inserted into larger DNA with the help of several recombinase DNAs that cut the mother molecule at a specific site. This helps in preparation of Recombinant DNA molecule with several modifications, useful in several medical or food purposes.

Answer 2

The correct answer is: separation of interlocked circular DNAs.

Conservative site-specific recombination is a type of site-specific recombination process that enables genetic recombination between DNA molecules. The two DNA molecules that exchange their parts contain short DNA sequences, which are bound by specific recombinase proteins. In this process, breakage and joining occur at two special sites, one on each participating DNA molecule. Depending on the orientation of the two recombination sites, conservative site-specific recombination can rearrange DNA in a form of DNA integration, DNA excision, or DNA inversion.
