Arrange the events in chronological order for the physical process of meiotic recombination.Prophase I of meiosis begins.Recombination is complete.Homologous chromosomes pair together.Enzymes break both strands ofDNA in one chromosome.The 3' overhang strand of DNA invades thedouble helix of the homologous chromosome.Enzymes resolve the Holliday junction.The duplexed strand of DNA serves asa primer for synthesis of new DNA.Enzymes degrade the 5' strands of DNA.

Here's the chronological order for the physical process of meiotic recombination:1. Prophase I of…

A cell goes through meiosis in order to separate a set of replicated chromosomes into two haploid cells and then to separate these cells again without copying the DNA to form four haploid cells.
