All human cells, with the exception of red blood cells, contain nuclear DNA (nDNA),whereas all human cells contain mitochondrial DNA (mtDNA). When reviewing a case or preparing for trial, prosecutors should keep in mind that biological evidence may not be visible to the naked eye. Police agencies must be trained to identify all sources and locations of potential biological evidence, seen or unseen. Standards 20.1 and 20.2 of the National Prosecution Standards, 2d Ed. (NDAA 1991) encourage prosecutors to assist and cooperate in training police to identify these sources and locations.
