The enzyme recombinase is required at which stage of meiosis?
Options:
Answer:
Solution:
The first phase of Meiosis 1 is ProphaseIt is further divided into five phases.Leptotene: Condensation of Chromatin material takes place in this stageZygotene: The homologous chromosome formation is seen in this stage and formation of synaptonemal complex occurs.Pachytene: At this point a tetrad of chromosomes is formed and this is known as bivalent. Crossing over is also seen in this stage Thus recombination nodules are formed which requires Recombinase enzymes.Diplotene: The synaptonemal complex degrades and chaismata formation is seen.Diakinesis: This is the final stage of Prophase. Here the chromosomes condense further. Four proper tetrads are visible. This marks the end of Prophase-1
