WebMeiosis reduces the number of chromosomes from diploid (2n) to haploid (1n) during the production of gametes. Meiosis begins with the duplication of DNA, producing four strands of DNA in two pairs of homologous chromosomes: 2(2n) becomes 4(n), that is, four haploid cells, where n is the number of strands of DNA in a chromosome.
WebAfter denaturation of DNA, the cells were stained by an indirect immunofluorescence method using a commercially available monoclonal anti-BrdUrd antibody or by propidium iodide. The relative fluorescence intensities of stained BrdUrd and double-stranded DNA were altered reciprocally by changing HCl concentration and/or denaturation time.
