Matthew K. Oki I.J. Week 4
Purpose
Methods & Results
- The formal methods were followed from Activity 2 of the Exploring HIV Evolution
Activity 2, Part 1
- Download the provided sequences of subjects 10-15 from BIOL368/F16:Week 4
- Upload these sequences into the Biology Workbench
- Run the multiple sequence alignment for the selected subjects and clones
- The subjects & clones below were used:
- The output results in the following uprooted tree:
- The clones on the tree seemed to cluster together.
Activity 2, Part 2
- Three individual subjects were run through multiple sequence alignment
- Each nucleotide difference (S) was denoted by the absence of a star as shown below with Subject 15:
- Theta was then calculated:
- Theta is an estimate of the average pairwise genetic distance
- The equation from Exploring HIV Evolution is given below:
- Min and Max difference were calculated:
- One subject's clones were selected and run through the same multiple sequence alignment
- Click on "Import Alignments"
- Go to the "Alignment Tool" tab
- Run a "Clustaldist" test
- A matrix is produced as shown below:
- The highest and lower numbers in this matrix were multiplied by the length of sequence
- Rounding these numbers to the nearest integer gives us maximum and minimum respectively
- This was performed for all 3 of the subjects picked above with the results in the table below:
- Finally, the min and max were calculated from a comparison of two subjects:
- The table below gives the results of three comparisons:
Scientific Conclusion
Defining Research Project
Question
Is there a genetic difference in HIV-1 in patients who contracted the virus sexually or by intravenous injection?
Hypothesis
We hypothesize that there will not be a genetic difference in HIV-1 in patients who contracted the virus sexually or by intravenous injection
