WebS is the period of DNA synthesis, where cells replicate their chromosomes. G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs. M is the actual period of cell division, consisting of prophase, metaphase, anaphase ... WebThe best studied mechanism for meiotic recombination involves a double-stranded break of one of the chromosomes initiated by the meiosis-specific endonuclease, Spo11.
