DNA Barcoding Flashcards
1
Q
Define DNA barcoding.
A
The use of short unique DNA sequences as an identification tool.
2
Q
Define taxonomy.
A
The discovery, description and identification of species.
3
Q
Define systematics.
A
Relationships among species.
4
Q
Define biodiversity.
A
Species, genetic, and ecosystem variation in an area.
5
Q
What is needed for DNA ‘barcoding’ regions to discriminate between species?
A
The DNA locus must differ between each species being studied. The regions must also be similar enough to be amplified, ‘aligned’ and compared.
6
Q
What are the criteria for picking a barcoding region?
A
Universality, robustness and discrimination.
7
Q
What are some applications of DNA barcoding?
A
DNA fingerprinting.
Taxonomic organisation.
