1) making haploid cell for sexual reproduction
2)it's long story u can read miosis in text books im sure u will undrestand it if u want I can suggest u some books
3)befor meiosis in interphase
in bacterial cells dividing cell into two control the number of chromosomes in cell in if binary fission takes long time the chromosome of bacteria will replicate again and cell will contain 3 chromosomes from main chromosome but in eukaryotic cell there is inhibition after dna replication that avoid cell to do that
4)2 times
5)I couldn't understand your question
