OUR TEAMLAB 1 WRITE-UPInitial Machine TestingThe Original Design The Open PCR machine is fairly easy to use. Simply plug it in to the USB port on your computer and turn it on. From your computer, you can adjust the temperature, add or remove steps to the process, and adjust the number of cycles.
When we unplugged the LCD from the Circuit Board, the LCD turned off. When we unplugged the white wire that connects the circuit board to heat block, the LCD was unable to accurately read the temperature.
The very first time that our group used the Open PCR machine was October 28, 2012. The process went fairly smoothly, which was unexpected. All we did was put the samples into the machine, set the peak temperature and number of cycles, then let it run for an hour and forty-nine minutes.
ProtocolsPolymerase Chain Reaction The polymerase chain reaction (PCR) is a biochemical machine used in biological chemistry to produce numerous copies of a particular piece of DNA, generating multiple duplicates of DNA sequences. The PCR machine works similar the cycle of DNA replication at the cellular level. The machine consists of four individual steps, initiation, denaturation, annealing, and extension. The initiation step is solely to prepare the DNA samples to be put through the thermal cycler program. During the denaturation step, the DNA strand is split into two separate strands. After, the annealing step is where the DNA primer attaches to the targeted DNA sequence. The primer only attached to a specific site on the strand, not necessarily the entire strand. The purpose of the primer is to mark the beginning and the end of the targeted DNA sequence. Lastly, in the extension step, the DNA polymerase is first activated, which begins to synthesize the DNA primer. This results in two double stranded target DNA sequences. The PCR machine cycles numerous times to amplify the specific sequence. In order to complete the reaction several components are required such as:

(Add your work from Week 3, Part 2 here)
Research and DevelopmentSpecific Cancer Marker Detection - The Underlying Technology (Add a write-up of the information discussed in Week 3's class) (BONUS points: Use a program like Powerpoint, Word, Illustrator, Microsoft Paint, etc. to illustrate how primers bind to the cancer DNA template, and how Taq polymerases amplify the DNA. Screen-captures from the OpenPCR tutorial might be useful. Be sure to credit the source if you borrow images.)
Results(Your group will add the results of your Fluorimeter measurements from Week 4 here)
