What does the Red color represent in a microarray analysis?
Genes turned on in cancerous cells
Genes turned on in normal cells
Gene turned down in cancerous cells
Genes not shown in cancerous or normal cells
What does the green color mean in a microarray analysis?
Genes turned on in cancerous cells
Genes turned down in normal cells
Genes turned down in cancerous cells
Genes present in cancerous and normal cells
What does the yellow color represent in a microarray analysis?
Genes turned on in cancerous cells
Genes turned on in normal cells
Genes turned on in both cancerous and normal cells
Genes neither cancerous nor normal turn on
What is represented by black or blank spaces in a microarray analysis?
Genes turned on in cancerous cells
Genes turned on in normal cells
Genes turned off in only normal cells
Genes turned off in both cancerous and normal cells
How does Marker Analysis work?
STR binds to a binding site right before a mutated gene
STR binds to a binding site after a mutated gene
STR binds to a binding site on the mutated gene
STR is not used in Marker Analysis
What is the props of Marker Analysis?
Although more expensive than DNA sequencing it produce exact sequence of gene
Although slower than DNA sequencing it produces exact sequence of gene
Marker Analysis is both cheaper and faster than DNA sequencing
Marker Analysis is more expensive but faster than DNA sequencing
What does Marker Analysis determine?
Which allele is most likely to be the cause of the mutated gene
Which allele is mostly not responsible for the mutated gene
What DNA sequence is responsible for the mutated gene
Marker analysis can’t conclude anything wrong with a patient.
If a patient had the fragment length of 0.4, how many base pairs would there be?
600
700
800
900
Which imaging system uses magnets to produce an image of bones, tissues, and organs?
X-ray
MRI
CT-Scan
Bone Scan
What do x-rays show?
Bones
Skin
Soft Tissue
Organs
Which imaging uses x-rays but rotates it on an axis to produce a 3-D image?
MRI
Bone Scan
CT-Scan
PET Scan
When would you use an x-ray?
When patient is suspected to have a bone fracture
When patient is suspected to have internal bleeding
When patients is having bowel issues
When trying to locate cancer
A patient is suspected to have a tumor but doesn’t want anything is be injected into their body, which scan could locate the tumor while not injecting things into their body?
PET scan
CT-Scan
Bone Scan
X-Ray
Which of the following shows an PET scan?
An oncogene is...
A gene that has created a different variation of itself .
A gene whose protein products prevent cell division, therefore preventing uncontrolled cell growth.
A gene with a potential to cause cancer but that requires some alteration.
A gene having the potential to cause a normal cell to become cancerous.
Which of these is NOT an abbreviation of a phase in the cell cycle?
C
G2
G1
S
What is a cancerous tumor called?
Malignant
Premalignant
Postbenign
Benign
What chromosome is the BRCA2 gene located on?
13
17
15
11
What part of the cell cycle shows Mitosis?
A
D
C
B
Given the Log2 numbers, which gene was induced by tumor formation?
Gene A: 1
Gene B:-2.34
Gene C: 3.62
Gene D: 0
Which genetic marker(s) is used to identify the BRAC2 mutation?
SNV
STR
SNP
All of the above
Which of the following shows sporadic cancer?
Caused only by environmental factors.
Occurs when parents who have mutations pass those mutations down to their offspring.
Occurs by chance from DNA mutations that can be passed down to offspring.
Caused by bad mutations in family bloodline or by environmental factors.
Which two answers describe a mutation?
A change in the amino acid sequence that does not change the DNA sequence.
A change in the DNA sequence that changes the amino acid sequence.
A change in the amino acid sequence that changes the DNA sequence.
A change in the DNA sequence that does not change the amino acid sequence.
