cycle and cancer.
What controls how often cells perform mitosis?
Chemicals called CYLCINS are responsible for the rate and
timing of cell division.

When these chemicals are not properly controlled (too
much or too little) cell division does not occur as
programmed.

development.

Standard 17-4

development.
What is a mutation?
Mutations are changes that occur in the genetics of an
organism, resulting in some physical or chemical change.
What are examples of mutagens (chemicals that causes
mutations)?
UV light, cigarette smoking, poor diet, pollution, alcohol.
How do mutations affect cancer development?
Mutations in the instructions for cell division can mess with
the production or release of cell CYCLINS, resulting in bad
mitosis.

of DNA of the original
cell/Meiosis reduces the

double/full amount of genetic
info for an organism; usually a
somatic (body) cell;
represented by 2N.

each gamete.

(paternal) DNA guarantees each gamete
will contain a UNIQUE combination from
each parent’s parent.

occurrence; the chance that any 2
gametes will join during conception.

a PUNNETT SQUARE to predict the
probability of genetic outcomes.
A PUNNETT SQUARE is a tool used by
