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.
Dissection is one of the procedures through which scientists can find out about the internal parts of life science specimens.
Dissection in its literal terms is the cutting down of an object. The process involves cutting the parts and organs of an organism to study its anatomical structures. The process should be performed carefully so that the anatomy is not ruined and results are not misinterpreted.
Specimens are the samples related to living organisms used to visualize and study about them. These specimens can be deceased living organisms that are carefully preserved using chemicals. Other structures of the living organisms like their teeth, skin, exoskeleton, horns, etc. can also be considered a specimen.
