title: Anomalous electrophoretic mobility of mouse mtDNA restriction fragments.
abstract: Analysis of the electrophoretic mobilities of mouse mtDNA restriction fragments revealed a high incidence of anomalous migration in polyacrylamide slab gels. Relative to the mobility predicted by the sequence, 6 of 29 200- to 700-bp fragments had deviations of 5-12%. Three of these fragments migrated more slowly than predicted while three were faster. There was little, if any, correlation between electrophoretic mobility and base composition. The anomalous restriction fragments mapped throughout the mitochondrial genome.
