Cambridge Reference Sequence

The Cambridge Reference Sequence (CRS) for human mitochondrial DNA was first announced in 1981. A group led by Fred Sanger at the University of Cambridge had sequenced the mitochondrial genome of one woman of European descent during the 1970s, determining it to have a length of 16,569 base pairs (0.0006% of the nuclear human genome) containing some 37 genes and published this sequence in 1981.
