The process by which
the nucleus of a cell is
divided into 2 identical
sets each with the same
number of
chromosomes.
Mitosis
What type of cells
undergo Mitosis?
Somatic Cells
Or
Body Cells
How many phases are
there to Mitosis and
what are they?
4 and they are
Prophase, Metaphase,
Anaphase, and
Telophase.
What is the name of the
protein disk that in
Metaphase the spindle
fibers attach?
Centromere
Chalones are a substance
that prevent or inhibit
mitosis. If you cut your
finger what would your
skin do increase or
decrease the amount of
chalones?
Decrease
This is a special
kind of cell division
where the number
of chromosomes are
cut in half?
Meiosis
A cell that has 23
chromosomes is
called
(hint: n)
Haploid
In meiosis the
process starts with a
diploid cell and
ends with what?
4 Haploid
How many
divisions of
Meiosis are there
and what are they
called?
2, Meiosis I &
Meiosis II
The exchange of
genetic material
in prophase I is
called?
Cross Over
These are rod
shaped structures
that form during
cell division.
Chromosome
The structure
that holds two
chromatids
together.
Centromere
What makes up
a chromosome?
2 Chromatids
How many
chromosomes
are in a
Somatic Cell
46 total or 23 Pairs
Two copies of each
chromosome that are
similar in shape, size,
and similar in genetic
information are called
what?
Homologous
Chromosomes
What phase
does the cell
spend most of
its life?
Interphase
How many
phases of
Meiosis are
there?
8
The phase where the
chromosomes line
up is called what?
Metaphase
What is the last
phase of Mitosis
and Meiosis I &
II
Telophase
Which phase
does crossover
occur?
Prophase I
What are the
two processes
by which cells
divide.
Mitosis &

How many
eggs are made
in Meiosis?
