A) nuclease
B) RNA polymerase
C) recombinase
D) DNA polymerase
Correct Answer: B
Solution :
The enzyme involved in the crossing-over or recombination between two homologous chromosome are believed to be site having multienzyme recombinase complex. Crossing- over or recombination occur between non- sister chromatids of a bivalent by breaking and reunion of chromatid segment with help of recombinase enzyme (Stem and Hota 1969-1978), Nicks may form gaps by means of enzyme nuclease (exonuclease) or heal up by means of enzyme ligase. RNA polymerase is need for the formation of RNA is protein synthesis from DNA template.
