Summary Introduction
Introduction
Mitosis is a nuclear division, in which one nucleus divides to gives two identical nuclei. Mitosis takes place only in a eukaryotic organism. It varies from organism to organism. Cytokinesis is the final stage of mitosis, where cytoplasm divides to form two new cells. Mitosis is essential for the normal growth and maintenance of an organism.

With regard to the process of mitosis, which of the following pairs is NOT matched correctly?
a. Interphase - the cell grows, chromosomes replicate, and proteins are produced to prepare the
cell to divide
Ob. Prophase - chromosomes condense, and the nuclear membrane dissociates/breaks down
c. Metaphase - chromosomes move toward opposite poles (or sides) of the cell
d. Anaphase - sister chromatids separate
e. Telophase - two distinct nuclei are formed; this is the stage immediately before cytokinesis
O O O
Identify the phase in mitosis in which the replicated sister chromatids line up in the centre of the cell.
Select one:
a. Anaphase
b. Telophase
