Sequence from the human genome project
Sanger Sequencing Lab Researchers at UW-Madison’s department of Ophthanmology and Vision Sciences have discovered a gene [“switch”] that turns off or on the development of the optic nerve of cave fish found in the Mammoth cave system in Kentucky. They are optimistic that understanding how this gene functions can be used to slow or even cure degenerative blindness in humans. Before human trials can begin, researchers must first test this gene in mice. In order to maintain this gene in the lab researchers want to ligate the gene into the p. UC 19 vector at it’s multi-cloning site [MCS]. Then clone the recombinant vector in E-coli for storage. Your role is to sequence the MCS so researchers can identify possible compatible restriction sites used in the isolation of the vision gene in the first place.

Name_______ Date________ Hour______ Reading Questions 1. What are the two approaches to DNA sequence analysis? Which one are we going to be looking at? One is a set of organic chemical reactions the other uses enzymes. The chemical method is tedious. We will be looking at autoradiographs produced from enzymatic reactions. 2. What is the difference between the four enzymatic reactions that are performed? “G” contains dideoxy. GTP , “C” contains dideoxy. CTP, “A” contains dideoxy ATP, “T” contains dideoxy TTP 3. What method is replacing the traditional isotopic method? Why? Non-isotopic methods of using fluorescent dyes and automated DNA sequencing machines. Why? These methods are better, more efficient. Radiation is SCARY! 4. What is the “nested set”? The products of the reaction. 5. How is the image from the gel transferred to the x-ray? What component makes this possible? The gel is placed directly on the x-ray film. DNA fragments have been labeled with 32 P.
