Question

Describe the four steps of mitosis: • Prophase: • Metaphase: • Anaphase: • Telophase:

Answer 1

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
