Lane 1, 4 and 5 represents 490/190 bp (I/D), Lane 2 represents 190 bp (II), Lane 3 represents 100bp DNA Ladder
Figure 1: Absence of the 287 bp intronic region in the ACE gene gives a 190bp fragment and 490 bp bands PCR product indicates heterozygous Insertion and deletion alleles are seen as 490/190 bp.
