Jonathan Lewis October 28, 2016 BSCI 222 (2125) Dr. Paczolt Ethical Controversy in Genetics Personal genomics is the process of sequencing and analyzing the genomes of  individuals. It can be achieved by sequencing thousands of single nucleotide  polymorphisms (SNPs). The information gathered can be very useful in determining the  risk of obtaining certain conditions. Huntington’s disease and breast cancer, for example,  have highly predictive genetic markers. With SNPs, however, these genetic markers can  be identified so the patient can be more cautious and receive more frequent checkups to  stay healthy. DNA sequencing is the process of determining the order of nucleotides in a DNA  molecule. One of the most common methods of sequencing is electrophoresis. DNA is  placed in the gel and a current is run through so that the molecules can move down. This  creates bands based on the size of the nucleotides. The results of the electrophoresis can  be used to determine the exact order of nucleotides in a DNA molecule (GNN, 2).  Single nucleotide polymorphisms are genetic variations of a single nucleotide.  They are very frequently found throughout a genome, occurring about once for every 300 nucleotides. Although these are usually harmless, some can dramatically affect a gene’s  function. According to the NIH, “

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
