Question

Which of the following process generates a new copy of the transposable element at a new location of DNA?

(a) Homologous genetic recombination

(b) Site specific recombination

(c) Non-homologous recombination

(d) Replicative recombination

I have been asked this question by my college director while I was bunking the class.

I would like to ask this question from DNA Recombination topic in section DNA, RNA and Protein Metabolism of Biochemistry

Answer 1

Right choice is (d) Replicative recombination

Explanation: Homologous genetic recombination occurs between DNA molecules of very similar sequences.

Site-specific recombination occurs between particular short sequences present on otherwise dissimilar parental molecules.

Non-homologous recombination occurs in regions where no large –scale sequence similarity is apparent.
