Figure 1: Restriction enzyme fragments of K121Q polymorphism using AvaII in 2% agarose gel electrophoresis. Lane M shows the 100bp genomic DNA Ladder; Lane 1&3 show the heterozygous fragments (208, 153 and 55 bp); Lane 5 shows a mutant fragment (155 and 53 bp) and Lane 2&4 show the wild type fragments (208 bp).
