Answer
-
Metaphase
-

-

-

Question 2
Question
What stain does G-banding use?
Answer
-
Giemsa
-
Chrome red
-
Methyl-blue
-
Green
Question 3
Question
G-banding can only detect large abnormalities. True or false?
Question 4
Question
What does FISH stand for?
Answer
-
Fluorescent in situ hybridization
-
Fluorescent in site hydrolysis
-
Familial in situ hybridization
-
Familial in situ hydrolysis
Question 5
Question
You don't need to know what abnormality you are looking for when using FISH. True or false?
Question 6
Question
Why do you need to know what abnormality you are looking for when using FISH?
Question 7
Question
How can you tell if there is an abnormality using the FISH technique?
Answer
-
Because some of the markers will not light up as they have not been able to anneal to bits of DNA sequence as they are missing
-
Because all of the markers will light up because there are specific sequences of DNA that cause genetic disorders
-
Because if there were no abnormalities the markers would not show up at all
Question 8
Question
FISH can show slightly smaller abnormalities than G-banding, but they still have to fairly large. True or false?
Question 9
Question

Answer
-
Quantitative fluorescence Polymerase Chain Reaction
-
Qualitative fluorescence polymerase chain reaction
-
Quantitative familial polymerase chain reaction
-
Qualitative familial polymerase chain reaction

Question 12
Question
What is the name for trisomy 18?
Answer
-
Pattau's syndrome
-
Edward's syndrome
-
Down's syndrome
Question 13
Question
What is the name for trisomy 21?
Answer
-
Pattau's syndrome
-
Edward's syndrome
-

Question 14
Question

-
Comparative genetic hydrolysis
Question 19
Question
How can you tell if there is an abnormality in the DNA when using array-CGH?
Answer
-
The relative fluorescence of the sample and control strand will be different
-
The relative radiation of the sample and control strand will be different
-
The length of the sample and control strand will be different when run through gel electrophoresis
Question 20
Question
Which two molecular biological techniques look at the actual base sequence when looking for genetic abnormalities?
Question 21
Question
Which of the following is cheaper and less time consuming?
Question 22
Question
Why do we only sequence exons when using sanger sequencing?
Answer
-
Because the introns do not code for proteins so are not important to us
-
Because it is time consuming and expensive
-
Because introns rarely have mutations that cause genetic diseases
-
Because we are unable to isolate the introns to sequence them
Question 23
Question
What machine is used in sanger sequencing to read the sequence of bases?
Answer
-
An electropheragram
-
A Geiger counter
-
A microscope
Question 24
Question
Not all changes to the base sequence cause disease. True or false?
Question 25
Question
Why is it better to use next generation sequencing when you don't know what you are looking for?
Answer
-
Because it is easy to sequence a whole genome
-
Because sanger sequencing would take too long
-
Because next generation sequencing is more accurate
-
Because next generation sequencing is less expensive
