Can you recall meiosis and indicate at what stage a recombinant DNA is made?


Recombinant DNA in meiosis is produced by crossing over. The crossing over occurs in the pachytene stage of prophase of the meiosis I. In this stage the sister chromatids are joined at the centromere as well as at the chiasmata. Chiasma is the position where the genetic recombination occurs by strand exchange.
