Question
Chapter 12, Problem 6TYKF
Summary Introduction
Introduction: Cell division is a natural process in which a parent cell divides to produce two daughter cells. Cell cycle is divided into interphase and mitosis.

Mitosis
(Name the cell division phase on the line.)
DNA and centrosomes are replicated.
Name:
Chromatin condenses and supercoils to form
dense chromosomes. Since DNA was previously
replicated, the chromosomes are now present
as paired sister chromatids. Centrosomes move
to opposite sides of the nucleus and will define
the orientation of the division.
Name:
DO
Estimate the duration of each phase of mitosis, identify which of stage of mitosis is the longest. Kindly include references (very important).
