Question

The enzyme recombinase is required at which stage of meiosis

Answer 1

Recombinase enzyme is involved in process of crossing over which occur in pachytene stage.
The previous chapter on mutation and repair of DNA dealt mainly with small changes in DNA sequence, usually single base pairs, resulting from errors in replication or damage to DNA. The DNA sequence of a chromosome can change in large segments as well, by the processes of recombination and transposition. Recombination is the production of new DNA molecule(s) from two parental DNA molecules or different segments of the same DNA molecule; this will be the topic of this chapter. Transposition is a highly specialized form of recombination in which a segment of DNA moves from one location to another, either on the same chromosome or a different chromosome; this will be discussed in the next chapter

Answer 2

Answer:

pachytene

Explanation:

crossing over leads to recombination of genetic material takes place in the pachytene stage
