Length variability (polymorphism) within the MR2 repeat.

1Machine-generated measurement of DNA length at the top of the observed peak, in nucleotide scale.2Peak width at half-maximal heights of both peak slopes, in nucleotide scale.3The peak width was between 4 and 5 nucleotides (half-maximal peak height for this sample was more than 4 nucleotides but less than 5). Analysis of the graphs from mixtures made of differing ratios produced a migration of the peak as expected, confirming a variation in the polymorphic forms of samples PN9 and PN104.
