"Universal" PCR primer design in the mtDNA ND3 region
The diagram shows
part of the DNA sequences
of the ND3 subunit gene from the mitochondrial DNA (shown 5'
3',
left to right) of four species of mammalian Carnivora:
three Canoids: Harbour Seal (Phoca), Grey
Seal (Halichoerus), and domestic dog (Canis),
and a Feloid domestic cat (Felis). The nucleotide region shown in colour
is a potential PCR primer site,
a region of >25 bp region that is identical between seal species
sequences and >92%
identity with the Canoid and (or) Feloid sequences. This primer,
paired with another a few hundred or few thousand bases away,
will likely amplify the gene region for most species of
Carnivora.
