Restriction map of White-Tailed Deer mitochondrial DNA
The mitochondrial DNA (mtDNA)
molecule of vertebrates is a circular molecule about 17,000 bp
(17 Kbp) in circumference. Double-digest
analysis of mtDNA from a White-Tailed Deer (Odocoileus
virginianus) identifies the positions of 33 six-base-pair
restriction sites from 10 different restriction
endonucleases (letter codes a, b, c,
e, f, h, j, x, y,
& z). This gives a restriction map of the
molecule based on 198bp, about 1% of the genome.
The restriction
map can be oriented to the functional map of gene regions in the
molecule by the placement of the two highly-conserved Sst
II sites [z] in the 12S
& 16s rRNA genes at an
interval of 1.6kbp. This map was part of one of the
earliest uses of restriction maps to look at relationships
within and between closely related species [SM Carr
et al. 1986. Proc Natl Acad Aci 83:9576] .
