What can we conclude from microarray data?
genes that cause cancer
genes that stop cancer
which genes may be affected in cancer
which cells have genes
What does the RED color indicate in DNA microarray?
these genes are not expressed in healthy cells
there are no genes in these cells
these genes are expressed in cancer
these genes are not expressed in cancer
What does the BLUE color indicate in DNA microarray?
these genes are expressed in cancer
these genes are expressed in healthy cells
these genes are not expressed in healthy cells
there are no genes in these cells
What does the PURPLE color indicate in DNA microarray?
this gene is expressed in cancer cells only
this gene is expressed in healthy cells
there are no genes in the cell
this gene is expressed in both cancer and healthy cells
Gene regulation is the process of doing what?
producing proteins
replicating DNA
producing RNA
determining which genes will be turned on or off
True or False: One example of gene regulation is when the cells from the breast do not produce insulin the way that the cells from the pancreas do.
True
False
True or False. Every body cell in your body contains the exact same chromosomes.
True
False
What is a specialized cell?
A cell that has different DNA
A cell whose structure is specialized for its function
Excretion of toxins
Different combinations of genes in the nucleus
Choose the correct order from smallest to largest.
nucleus-cell-organ-tissue-DNA
organ-tissue-cell-DNA-nucleus
DNA-cell-nucleus-organ-tissue
DNA-nucleus-cell-tissue-organ
An oncogene is a gene that
produces proteins that slow cell division
is over-expressed in cancer
repairs errors in DNA
is normally present and active in all cells
A proto oncogene is
a gene that codes for a protein
a gene that initiates and regulates the production of RNA for genes
a hole that is poked into the bacterial cell membrane
a normal gene that controls cell growth
Tumor suppressor genes
slow down the rate of cell death
control the rate of cell division and cell death
produce factors that control aging
enable cells to grow out of control
What is an analogy of a mutated tumor suppressor gene?
Gas pedal stuck on
Lights not working
Brake pedal not working
Gas pedal not working
What is an analogy of an oncogene?
Gas pedal stuck on
Lights not working
Brake pedal not working
Gas pedal not working
Which MUTATED gene would you expect to be expressed in cancer cells?
KRAS- Helps regulate cell division by encouraging cell growth
INS-Supports the body using sugar from our food for energy
GAPDH- Provides cell with energy by breaking down sugar from our food
PNLIP- Supports the digestion and breakdown of the fat we eat
Which gene would you expect to be BLUE on a stomach microarray?
CSN2- Supports production of milk
KRT10- Provides strength & protection to skin, hair, and nail cells
PGA4- Supports the digestion and breakdown of the protein we eat
LALBA- Regulates the production of lactose in breast milk
