Explanation

A. Metaphase Spindle fibres attaches to kinetochores of chromosomes Chromosomes are moved to spindle equator and get aligned along metaphase plate through spindle fibres of both poles B. Telophase Chromosomes cluster at opposite spindle poles and their identify is lost as discrete elements Nuclear envelope assembles around the chromosome clusters Nucleolus, Golgi complex and ER reform C. Interphase It is the duration which is a variable depending on the function of cell. Just before nuclear division, the DNA of chromosome replicates thus, it becomes doubled. During this phase, chromosome material is in the form of very loosely coiled threads called chromatin
