Question 4
Question
How are physical maps made?
Answer
-
Design markers that overlap along the genome
-
Orientation of homologous chromosomes
-
Allele studies
Question 5
Question
Physical maps must be made of physically isolated parts of the genome
Answer
- True
- False
Question 6
Question
A genetic marker acts as a reference point in a linkage study
Answer
- True
- False
Question 7
Question
Genes are usually used as markers in non-human studies. Why can they not be used in humans?
Answer
-
Human genes are more unstable
-
Human genes vary too much
-
Human genes are more highly conserved
Question 8
Question
What is the preferred form of marker in humans?
Answer
-
Polymorphic introns
-
Polymorphic Exons
-
SNP's
Question 9
Question
More polymorphic DNA= less useful
Answer
- True
- False
Question 10
Question
Homozygotes are more useful in genetic mapping than heterozygotes
Answer
- True
- False
Question 11
Question
How must markers be placed along the chromosome?
Answer
-
Evenly spaced
-
As lightly as possibly
-
As densely as possible
Question 12
Question
The aim it to combine genetic and physical maps
Answer
- True
- False
Question 13
Question
Once you have a marker with a high linkage to a disease/trait, how do you use the physical map?
Answer
-
Find the marker and look for genes very close to it
-
Find the suspect gene and look for markers very close to it
-
Find the marker and look for genes as far away as possible
