stages of mitosis

Question 1

Prophase

Answer 1

The cell is preparing to divide. Chromosomes outside of nucleus have duplicated and begin moving away from another toward opposite ends of the nucleus.

Question 2

Pro metaphase

Answer 2

the spindle fibers attach to the centromeres as the chromosomes continue to shorten and thicken. Most likely placed in nucleus.

Question 3

Metaphase

Answer 3

the nuclear envelope is fragmented and spindle occupies the region formerly occupied by the nucleus. The chromosomes are now in the center of the spindle with two sister chromatids.

Question 4

Anaphase

Answer 4

the centromeres uniting the sister chromatids divide. As chromosomes, they separate and move towards opposite poles of the spindle. this ensures that each cell receives a copy of each type of chromosome completing the genes.

Question 5

Telophase

Answer 5

the chromosomes arrive at the poles. The chromosomes become indistinct chromatin again. The spindle fibers disappears as the nuclear envelope components reassembles in each cell.
