Genetic fingerprinting Flashcards
(7 cards)
1
Q
Are DNA probes used in genetic fingerprinting?
A
YEs
2
Q
What does VNTRs stand for
A
Variable Number Tandem Repeats
3
Q
Non coding base sequences
A
Sequences of bases between genes that do not encode for a polypeptide
4
Q
What are VNTRs?
A
Repetition of Short base sequence found in non coding sections between genes in DNA
5
Q
Core sequence
A
The short base sequence that itself is repeated
6
Q
Why can VNTRs be used for genetic fingerprinting?
A
In a given species, all individuals have the same VNTR loci with the same core base sequence
For the particular locus on a chromosome
But between individuals the number of repeats shows a lot of variation
