Genetic recombination is catalyzed by many different enzymes. Recombinases are key enzymes that catalyse the strand transfer step during recombination. RecA, the chief recombinase found in Escherichia coli, is responsible for the repair of DNA double strand breaks (DSBs). In yeast and other eukaryotic organisms there are two recombinases required for repairing DSBs.

WebJul 19, 2024 · Recombination is an integral part of the pairing of homologous chromosomes. It occurs between non-sister chromatids during the pachytene stage of meiosis I (the first stage of meiosis) and possibly before, when the homologous chromosomes are aligned in zygotene (Figure 8.3). The crossovers of recombination are visible in the diplotene phase. WebMar 24, 2011 · The small cell, called the first polar body, contains almost no cytoplasm, but still sequesters the other half of the genetic material.
