The process of mitosis is divided into six stages. Interphase Prophase Metaphase Anaphase Telophase Cytokinesis
Interphase
Interphase G1
In this phase, the cell increases in mass in preparation for cell division.
S The period during which DNA
is synthesized
G2 The cell synthesizes proteins
and continues to increase in size.
Description The chromosomes are
identical chromatids connected at the center by the centromere.
Nucleolus disappears. Centioles duplicate to
form two pairs of centrioles.
Prophase
Metaphase Metaphase can occupy a
large portion of the total time of mitosis.
End of Anaphase Each pole contains a
complete compilation of chromosomes.
Anaphase
Telophase Description
the re-forming of the nuclear envelope
the sister chromatids reach opposite poles
Process With the two nuclei already at
opposite poles of the cell, the cell cytoplasm separates.
The contractile ring defines the cleavage line for the cell.
Cytokinesis
Meiosis is a two-part cell division process in organisms that sexually reproduce.
There are two phases. Meiosis I Meiosis II
Phase I Interphase
The cell undergoes a round of chromosome replication.
Prophase Each replicated chromosome pairs
with its corresponding homologous.
Metaphase Paired homologous chromosomes
line up at the center of the cell.
Anaphase Spindle fibers pull each
homologous chromosomes pair toward opposite ends.
Telophase A nuclear membrane forms
around each cluster of chromosomes.
Cytokinesis Forms two new cells.
Phase II Prophase
The chromosomes each containing two chromatids become visible.
Metaphase II, Anaphase II, Telophase II, Cytokinesis The final four stages of meiosis II are similar to those in meiosis I. However the result is four haploid daughter cells.
Four haploid cells
Mitosis Meiosis
Definition A type of cellular reproduction in which the number of chromosomes are reduced by half through the separation of homologous chromosomes.
A process of asexual reproduction in which the cell divides in two producing a replica.
Type of Reproduction Sexual Asexual
Function Sexual Reproduction Cellular Reproduction
Genetically Different Identical
Crossing Over Yes No
Chromosome Number: Reduced by half Remains the same
Number of Haploid Daughter Cells Produced
4 2
Cancer A disorder in which body cells lose the ability to control growth. Cancer cells grow rapidly and need to copy their dna more quickly
than normal cells. Cancer is a disease of the cell cycle.
Mutations Heritable changes in genetic information. Cancer can result from mutations.
Ex: Sickle Cell Disease.
