PROPHASE ;
1 . chromatin condenses to chromosomes .
2 . centrioles present in the cell duplicates and migrate to opposite poles .
3 . centrioles start making spindle fibres with the aggregation of tubulin protein
4 . nuclear envelope and nucleolus degrades
METAPHASE ;;
chromosomes align along equatorial plate of cell forming metaphase plate
ANAPHASE''
chromosomes are pulled towards respective poles and sister chromatids no w becomes sister chromososmes , two sets of chromosomes are formed
TELOPHASE;;
nuclear envelope forms around each set of chromosomes and chromosomes un coil to chromatin nuclear division is completed
