An Inside Look at Cancer
cancer results from the damage to _____ - answer genes
are the cases of cancer uniform throughout the world? include one example - answer
no, there are different percentages of cases
~higher cancer rates in cities -- more people
what are three environmental factors that could potentially cause cancer? – answer
pollutants, radiation, pesticides
most cancer-causing agents are _____ _____ - answer powerful mutagens
powerful mutagens are - answer substances that can damage DNA
how many mutations are required to cause cancer - answer few gene mutations to
transform a healthy cell into a cancerous one
what analogy is used to describe how cell replication is regulated - answer when you
drive a car
~the gas (stepping on the accelerator) signals the nucleus to replicate cells.
~the breaks signal the nucleus to stop replication
how do cells receive signals to divide? what is the importance of proteins - answer relies
on signals from proteins
~network (group) of proteins that rely messages to one another
there are genes for signal carrying proteins called ______ - answer oncogenes
once is Greek for - answer “tumor" or "mass"
if oncogenes are damaged or mutated, and become more active: - answer cancer can
can result
what does the reading compare to stepping on the accelerator of a car? - answercell
division starting
at the nucleus, the signal to _______ will override another set of genes that act as the
"brakes" - answerdivide
braking genes are also called: - answertumor supressor genes
