2. PRAYER
(Our Father)
Our Father who art in heaven,
Holy be your name, your kingdom come,
your will be done on Earth at is in
heaven…..
Give us these day our daily bread and
forgive us our sins, as we forgive those
who sinned against us,
Do not bring us to the test, but deliver us
from evil….
Amen…..

3. Good Morning
Class !
Just stay tune and
learn a lot
today……

4. Is everybody
Present ???

5. Let’s watch a short video
clip for you to motivate
what is our lesson all
about today……..

6. The Four
Stages Of
Mitosis

7. What is Mitosis?
Mitosis is a form of nuclear division
that produces daughter nuclei
containing the same number of
chromosomes as the parent
nucleus. The daughter nuclei are
genetically identical.

8. Chromosomes
Chromosomes are made up of the
molecule deoxyribonucleic acid (DNA).
DNA stores all the information that a cell
needs in order to grow and to carry out
vital activities. This information is stored as
sections of DNA or genes. The daughter
cells produced by mitosis are genetically
identical to the parent cell.

9. Stages Of Mitosis
Process of mitosis can be divided into 4
stages:
1. Prophase
2. Metaphase
3. Anaphase
4. Telophase

10. Prophase
Chromatin threads
condense, coil and shorten
to become chromosomes.
Each chromosome consists
of two sister chromatids
attached at the
centromere. The
chromosomes are now
visible under a microscope
as x-shaped structures.

12. Metaphase
Chromosome line up
along the equatorial
plane of the spindle.
The centromere of
each chromosome is
attached on both
sides to a spindle
fiber.

14. Anaphase
Each centromere
divides. The spindle fibers
shorten and pull the
chromatids apart to
opposite poles of the
cell. One the chromatids
are separated, they are
called daughter
chromosomes.

chromosomes

16. Telophase
Spindle fibers break
down. A nuclear
envelope forms around
the chromosomes at
each pole of the cell. A
nucleolus reforms in
each nucleus and the
chromosomes uncoil
and lengthen to
become thin chromatin
threads.

20. Question and Answer:
1. How can you distinguish each
stages of mitosis?
2. In your own idea, what is the
significance of these four
stages of mitosis in our lives?

21. Assignment:
In a ½ crosswise sheet of paper,
write a learning insight about the
four stages of mitosis, at least
three (3) paragraphs. Then, have
an advance study for our next
topic.

22. Goodbye class!
Thank you for
coming…
Class dismissed.
