The diagram below shows the map of a gene; boxes represent exons, and lines represent intergenic regions. Xba I sites and the distances between them are shown. A region corresponding to a probe used for Southern blotting is shown. In allele b, the indicated region is deleted. In allele c, the second Xba I site is mutated from AGATCT to AGAACT. Kate has genotype b/+; Mark has genotype c/c. Indicate the lanes containing Kate’s DNA and Mark’s DNA. iClicker Question 1:
