• produce gametes.
• help the organism grow/repair/replace somatic cells.
b. Mitosis produces ____ (number) cells that are: identical / unique (circle one)

___, ___
e. True / False: Homologous chromosomes line up side by side during metaphase.
(Careful, this one’s tricky…)
f. True / False: Sister chromatids are pulled apart during anaphase.

of DNA. This trading of DNA is called c_________________ o__________.
4. Cancer
a. Cancer is really uncontrolled m_____________________.
b. In a healthy cell, the g__________________ a__________________ gene (p53) helps
the cell correct mutations and directs the cell to suicide if the mutations are
irreparable. In most cancers, the p53 gene is malfunctioning (due to a mutation in
THAT gene).
c. A gene that leads to cancer (because of a mutation) is called a: proto-oncogene /
oncogene (circle one).
