Question

In conservative site-specific recombination, what is the name of the DNA sequence flanked by the recombinase recognition sequences?
-inverted repeat

-synaptic complex

-crossover region

-transposable element

-direct repeat

Answer 1

Answer:

The correct answer will be option-Crossover region

Explanation:

Recombination is a complex process which leads to the exchange of the genetic material between sister chromatids.

The recombination process is mediated by the recombinase enzyme which recognize the specific sites and allows the formation of the protein-DNA complex called synaptic complex.

The synaptic complex contains the short asymmetric sequence called the crossover region, which represents the rejoining and the DNA cleavage site.

Since crossover region represents the recognition sequence which is flanked is known as the crossover region.

Thus, the crossover region is the correct answer.
