Journal Entry #1
• What kind of superhero would you be if
you could genetically get superpowers?
• Why?

found  Genetic Mutations lead to a

Describe what it would be like
to be a geneticist without the
knowledge of DNA.

Why is it so important that
cells divide?
Revisit DNA
• What is a chromosome?
• How would you describe the unique
structure of DNA?
• What exactly is DNA replication?
Most importantly….
Why is DNA called the “Blueprint of Life”?
Every cell in our body has the
same DNA…specific to us!
• How do cells do that??
• Cells double their genetic information
through DNA replication, and then
divide….resulting in 2 cells, exactly the
same! This process is called MITOSIS.
• Why do cells divide? (why do we need
MORE cells)
– Organisms GROW... And need more cells.
– Replace dead cells.

Mitosis Diagram
• Cut out the phases of mitosis and place
them in order in your science notebook
• Use pages 58-59 in your textbook.
• Read about each phase and summarize
the key facts about each next to the cutouts on your poster.

Read Articles and share
• Four articles are at your table… each person will
become an EXPERT on that article –

• Take note on your worksheet
• Share your information and teach the other
people!
• Everyone should have the key parts of each
article on your notes sheet when we are done
How to Pick out key points
“Sharing in Short Hand”
• “Cancer is a disease in which abnormal cells are
able to invade healthy tissue”
• “There are more than 100 different types of
cancer”
• A Benign tumor is a tumor that is non cancerous,
can be removed and does not spread to other
parts of the body?
What is cancer?
Cancer is a disease in
which cells grow and
divide uncontrollably (like
weeds in a garden).
Cancer damages the
parts of the body around
it.
Cancer begins with a
mutation in the DNA. A
mutation is damage that
Mutations
Can begins when
mutations disrupt the
normal cell cycle,
causing cells to divide in
an uncontrollable way.
Cells begin to grow too
large, and divide too
often.
As more and more cells
grow uncontrollably, the
How does cancer spread?
It can take years for a
tumor to grow. As time
passes, tumors become
more and more
abnormal.
Sometimes cancer cells
can break from the
tumor. They may enter
the bloodstream.
Cancer can then be
Cancer Treatment
Surgery: this is the best
way to remove cancer
from the body IF it has
not spread to other parts
of the body.
Radiation: beams of
high-energy waves that
kill cancer
Chemotherapy: use of
drugs to treat cancer.
Important Cancer
Terminology
Benign Tumor: a noncancerous tumor that
does not grow or
progress.
Malignant Tumor: a
cancerous tumor that
progresses in size and
can be very potentially
dangerous.
Metastasis: the spread
There are many kinds, and
causes, of cancer.
Some cancers are
heritable.
Some are caused
by lifestyle.
Some people are
born with
mutations in their
DNA that cause
cancer.
Other times a
The bad news.
In 2009 about 1.5 million
people were diagnosed
with cancer.
In the US, cancer
accounts for nearly 1 in
every 4 deaths.
Cancer is the 2nd most

The good news.
Many kinds of cancer can
be prevented.
If caught early on, it is
possible to survive cancer
through a variety of
available treatments.
Scientists know more
about cancer than ever

People young and old are affected by
cancer.
Skin cancer, lung cancer, and breast cancer are
among the most common types of cancer found in
adults.
Leukemia, cancer of the bones or bone marrow, is the
Live healthy!
You can reduce
the likelihood of
getting cancer by
taking care of your
body!
- wear sunscreen.
- don’t smoke
- eat right
- stay active
Hope for the Cure
Billions of dollars are
spent on cancer
research every year!
Technology today is
more advanced and
better than ever.
Doctors are increasing
their knowledge of
