RNA is harvested from normal cells and tumor (cancer) cells, and
analyzed
using gene expression microarray analysis. The expression level
(transcript
abundance) of twenty genes is found to be significantly reduced in
the tumor cells
when compared to the level in the normal cells. Select from the
gene list (below)
the types of genes that might be included in this list of twenty.
Select all that are
correct (there may be 0-4 that are correct).
gene list
a. A tumor suppressor gene
b. An oncogene
c. A gene necessary for a cell cycle checkpoint
d. A gene necessary for DNA replication
