OUR TEAMLAB 1 WRITE-UPInitial Machine TestingThe Original Design (Write a paragraph description for visitors who have no idea what this is) Experimenting With the Connections When we unplugged the LCD screen (part 3) from the Open PCR circuit board (part 6), the screen went blank the machine had no visual output.
We first tested the PCR machine on Wednesday October 24, 2012. The easiest part was dealing with the set up of the cycles for the reaction. The program was pretty self explanatory and very easy to use once you knew all of the parts. The PCR machine itself was fairly easy to deal with as well. The only problem that we encountered was that the lid seemed somewhat hard to open and close because we weren't sure how stable it was going to be or if it would break.
ProtocolsPolymerase Chain Reaction 1. A Polymerase Chain Reaction(PCR) is used to amplify a single piece of DNA. The steps that lead up to the replication of a DNA sequence are denaturation, annealing, and extension which involve several different cycles ranging in terms of both length of time and temperature. This results in the exponential replication of a certain sequence of DNA.

Research and DevelopmentSpecific Cancer Marker Detection - The Underlying Technology A single nucleotide polymorphism is a variation in a single DNA nucleotide. The four DNA nucleotides are represented using the letters A, T, C and G. These variations occur normally throughout DNA and represent the most common form of genetic variation among people. They occur at a rate of 1 per every 100 to 300 bases along the 3-billion-base human genome. SNPs are point mutations that have been evolutionarily successful enough to recur in a significant proportion of the population of a species. In other words, SNPs are evolutionarily stable, meaning they do not change much from generation to generation. This allows SNPs to be considered highly conserved within the population and therefore serve as ideal biological markers for genetic research. In order for a sequence variation to be classified as a SNP it must occur in at least 1% of the population. Millions of SNPs have been identified in the human genome and cataloged in accessible databases. SNPs can occur with a gene, which is the coding region of DNA, or in a non-coding region. Because only about 3-5% of DNA actually codes for the production of proteins, most SNPs are found within non-coding regions. Since SNPs can be located near a gene associated with a certain disease, or occasionally within that gene, researchers have been able to pinpoint various diseases on the genome map. SNPs found within a gene, or somewhere in the regulatory region of a gene, are of particular interest because they are more likely to alter the biological function of the gene and therefore, the function of the protein. It is important to remember that SNPs do not cause or identify a disease state directly, but allow for the possible diagnosis or assists in determining the likelihood that someone will develop a particular illness. They also have the ability to help predict an individual’s response to certain drugs, environmental factors, chemicals, toxins, etc. In fact, since SNPs occur most frequently in the non-coding regions of DNA, they do not produce physical changes in people and have no effect on health or development. (Written by Kim L, Posted by William L). Polymerase Chain Reaction and SNPs A polymerase chain reaction experiment uses a set of nucleotide primers to amplify a specific section of DNA. Specifically, this diagnostic is testing for the presence of the cancer-linked rs17879961 SNP mutation. Since this SNP creates a new DNA sequence, primers can be made to only bind to the mutated DNA sequence. As a result, the PCR test can be run with a unique primer that will only bind if the target DNA shows rs17879961 mutation, allowing the test to identify the presence or absence this cancer-linked SNP. In rs17879961, there is an anomalous A-T pair that creates a new and unique DNA sequence specific to this cancer-linked mutation. Thus, only a specific primer will bind to the targeted sequence and, as a result, the PCR will only react if the specific mutation is present.
