Step-by-step explanation:
prophase-chromosomes are copied as the DNA replicates, parent cell have four chromosomes (two homologous pairs)
end of prophase- two sister chromatids make up each chromosome, the are joined by centromere
metaphase- spindle fiber is formed, and chromatides attach to it by centromere
anaphase- spjndle fibre shorten and pull the chromatids to opposite ends.
telophase- two new nuclei form at the poles of the cell. each has a copy of each chromosome from parent cell, two new cell separate an d the chromosome unravel as the cell goes back in to interphase.
the nuclear membrane and nucleolus also reappear. they were disappeared in the satge of prophase.
i think this will help you !✌
