PORTAGE GENETICS
MODULE 7 TESTS WITH
RESOLUTIONS.
, define cancer - correct ans:a genetic disease that causes mutations in
somatic cells
What are the 2 ways cells can be altered to cause cancer? - correct ans:1.
expression of abnormal genes
2. over expression of normal genes
define proliferation - correct ans:over expression of normal cells
What are some of the genetic alterations made to a chromosome that can
lead to cancer - correct ans:-deletion
-amplification
-rearrangement
most cancers are derived from the mutations of genes that control: - correct
ans:-DNA repair
-Cell division
-cell death
For something to be cancer, what two properties must it exhibit - correct
ans:1. uncontrolled, abnormal bell growth and division (proliferation)
2. defects in the restraints to keep them localized to one part of the body
(metastasis)
a cell that loses control over its growth but does not metastasize is called -
correct ans:benign tumor
A tumor breaks off into the bloodstream and invades other tissues and forms
masses, these masses are called - correct ans:secondary tumors
