Fig. 1From: Association between an angiotensin-converting enzyme gene polymorphism and Alzheimer’s disease in a Tunisian populationAgarose gel electrophoresis of PCR amplified products of the ACE (I/D) gene polymorphism. M represents 100-bp DNA ladder; lane 3 as DD genotype (190 bp); lane 2, as II genotype (490 bp) and lane 1, as ID genotypes (490 and 190 bp) of the ACE geneBack to article page
