| 摘要 |
In a method for determining the existence of a mutation in a nucleic acid fragment from an electrical signal generated by a DNA sequencer made up of sequence information produced by fluorescent fragment products of different lengths of said nucleic acid fragment, followed by a run-off peak produced by fluorescent full length fragment products of said nucleic acid fragment, any difference between said run-off peak and a reference run-off peak generated by unmutated full length fragment products of said nucleic acid fragment, is determined, a difference indicating the existence of a deletion or insertion mutation.
