16
Q

metaphase

A

chromosomes line up on metaphase plate

17
Q

anaphase

A

separation of genetic material, sister chromatids (chromosomes) pulled to opposite poles by spindle apparatus

18
Q

early telophase

A

chromosomes reach opposite ends of the cell

19
Q

cytokinesis

A

division of the cytoplasm into 2 cells, chromosomes reach the opposite poles and clump, events of prophase are reversed (chromosomes to chromatin, nucleolus and nuclear membrane reform, spindle apparatus dismantled)
