Mitosis

Question 1

What is mitosis?

Answer 1

Mitosis is a form of cell division in which two daughter cells that have the same number of chromosomes as the parent cell and each other.

Question 2

When does DNA replication take place?

Answer 2

Interphase.

Question 3

Describe the stages of Mitosis.

Answer 3

=Interphase
-DNA replication
-Increase in ATP
-Cell physically grows larger

=Prophase
-Chromosomes become visible
-Centrioles move to opposite poles of cell
-Spindle fibres develop
-Spindle apparatus form

=Metaphase
-Chromosomes attach themselves to the spindle apparatus by their centromeres

=Anaphase
-Centromeres split and splindle fibres pull chromatids apart to opposite poles

=Telophase
-Chromosomes reach poles and nuclear envelope reforms around chromosomes (Forming a new nucleus)

Question 4

Why is Mitosis important?

Answer 4

Mitosis is important for three key reasons:
-Growth
-Repair
-Reproduction
