The enzyme recombinase is required at which stage of meiosis:

Step-by-step solution

The characters of Pachytene/Pachynema are as follows- Crossing over i.e. exchange of segments between non-sister chromatids of homologous chromosome occurs at this stage. Chromatids of pachytene chromosome are attached with centromere. A tetrad consists of two sets of homologous chromosomes each with two chromatids. Each tetrad has four kinetochore (two sister and two homologous). A number of electron dense bodies about 100 nm in diameter are seen at irregular intervals within the centre of the synaptonemal complex
