The complete mitochondrial DNA sequence of Crotalus horridus (timber rattlesnake).

The complete mitogenome of the timber rattlesnake (Crotalus horridus) was completed using Sanger sequencing. It is 17,260 bp with 13 protein-coding genes, 21 tRNAs, two rRNAs and two control regions. Gene synteny is consistent with other snakes with the exception of a missing redundant tRNA (Ser) . This mitogenome should prove to be a useful addition of a well-known member of the Viperidae snake family.
