Document Summary

Lecture 26, 2/4/18, genomics ii: dna fingerprinting and dna microarray. Prophase i of meiosis: results in one chromosome with extra repeats of a sequence and one with fewer repeats, this leads to variety in a population. Example problem: pcr amplification and gel electrophoresis are performed for the same vntr locus in individuals 1 and 2. Canvas: https://canvas. emory. edu/courses/38826/external_to ols/90: smaller vntr regions correspond to shorter bands (closer to positive end of gel) Dna fingerprinting can be applied to forensics and paternity disputes. Retrieved from echo alp on canvas: https://canvas. emory. edu/courses/38826/external_tools/90: answer: lane 5 because its upper band is the same length as a band from. Individual 1 and lower band is the same length as a band from individual 2 (it has a band from each parent) Example question: which lane in image above contains info that might be of concern to.
