[Instructions: Describe how to set up your camera in front of the fluorimeter. Add a PHOTO of this set-up for bonus points.]
Place the camera in the cradle and set it 4cm away from the fluorimeter. Place plates under the fluorimeter so that when looking through the camera the slide is at eye level and the back of the slide can not be seen.

Placing Samples onto the Fluorimeter
Step one, Turn the fluorimeter light on and pull the slide so that the light shines in the middle of two dots on the slide
Step two, Get a new tip on the micro pipette and place 80mL of the SYBR Green I on the slide in between two dots on the slide. Dispose of this tip in the plastic cup .
Step three, Replace micro pipette with a new tip and place 80mL of the DNA sample onto the SYBR Green I dot
Step four, Set camera timer and close the box so that no light can enter when the timer goes off and the picture is taken. Take three pictures this way.
Step five, Remove the sample from the slide using the micro pipette and dispose of it in a plastic cup along with the tip
Step six, Push slide so that the next row of dots is in the lights pathway and complete steps two through five using your next desired DNA sample

SNP Information & Primer Design
Background: About the Disease SNP
SNP is a variation associated with the gene KCNE2. KCNE2 regulates neurotransmitter release, heart rate, insulin secretion, neuronal excitability, epithelial electrolyte transport, smooth muscle contraction, and cell volume. This SNP variation is located on chromosome 21:34370656 . This SNP variation is significant because it is pathogenic and linked to the disease congenital long QT syndrome. This disease can cause heart rhythm disorders.
Primer Design and Testing
We found the numerical position of the SNP to be 34370656. From this position we found the non-disease forward primer to be 5’-CATGGTGATGATTGGAATGT. From the position 200 bases to the right of the SNP we receive our non-disease reverse primer which is 5’-CCCTTATCAGGGGGACATTT. From this information we were able to determine our disease forward primer to be 5’-CATGGTGATGATTGGAATGC and our disease reverse primer to be 5’-GAACACATTATTGGCTTTAA. When we tested for the non-disease reverse and forward primers using the In-Silico PCR we got a result that matched to chr21:35742936+35743155. When we tested for the disease reverse and forward primers we got no result.
