Monkey (CV-1) mitochondrial DNA contains a unique triplication of 108 bp in the origin region

A fragment of monkey kidney cells (CV-1) mitochondrial DNA (mtDNA) containing the origin of replication has been cloned and sequenced. The nucleotide sequence, 640 bp, extends from the coding sequence of phenylalanyl tRNA to the flanking sequence upstream of the origin region. A unique triplication of 108 bp, including the evolutionary conserved sequence CSB-3, was found. Comparison between the origin regions of monkey, human and mouse mtDNA is presented.
