Topic 2 :: mtDNA Laboratory Analysis
DNA Sequences
DNA sequences are visualized in an electropherogram. Colored peaks are labeled "A," "C," "G," "T," and occasionally "N" (when the sequence detection instrument cannot designate a specific nucleotide). In a typical mtDNA analysis, about 700 nucleotides are analyzed for each sample. The electropherogram can be seen on a computer screen or printed out on paper.
