2. Restriction Enzyme Mapping - use any resources to assist you including the hints below. A circular plasmid molecule (12,000 total base pairs in size) was cut with a series of restriction enzymes and the digestions were size fractionated by agarose gel electrophoresis. Some digestions involved just one enzyme (single digest), some combinations of two enzymes (double digests), and one utilized all three enzymes (triple digest). Agarose gel electrophoresis of the digestions produced bands of the following sizes. Enzyme EcoRI Hindi!! Pstl EcoRI and Hindill EcoRI and Psti Hindill and Pstl EcoRI, Hindill, and Pst I Bands of the Agarose Gel (size in base pairs) 2300 and 9700 4000 and 8000 12,000 800, 1500, 2500, and 7200 2300, 3200, and 6500 4000 800, 1500, 2500, 3200, and 4000 I Draw a plasmid map showing the location of the restriction enzyme sites relative to each other for each map.

4. Animation 12.4: This table shows results from a genetic test conducted on DNA samples from two patients. The patients are a newly married couple seeking genetic counseling about their risks of passing on a genetic disease to any children they may have in the future. The samples included the DNA region including and immediately surrounding a single gene. Restriction enzyme cleavage analyses were performed on the samples. Female Patient 1) 3400 bp fragment Male Patient 1) 1600 bp fragment 2) 1800 bp fragment 3) 3400 bp fragment DNA fragments on gel What do the genetic test results indicate about this case? O Both the woman and the man are homozygous for the mutation. O Both the woman and the man are heterozygous. O The woman is homozygous for the mutation and the man is homozygous for the normal gene. O The woman is homozygous for the mutation and the man is heterozygous.
