The spireme stage of chromosomes is associated with:

Centromere splits and chromatids separate; this is a characteristic of which phase?

At which region do the spindle fibers attach to the chromosome?

Match the following and select the correct option:
$List-I$ (Phase) | $List-II$ (Event)
$(A)$ Prophase | $(i)$ Centromere attaches to spindle fibers
$(B)$ Metaphase | $(ii)$ Spindle fibers disappear
$(C)$ Anaphase | $(iii)$ Formation of spindle fibers
$(D)$ Telophase | $(iv)$ Spindle fibers shorten

During mitosis,$ER$,nucleolus,and other cell organelles begin to disappear at

During mitosis, chromosomes move to their respective poles in a stage called:
