Revision as of 19:58, 17 June 2010
We need to start capturing what we are doing, and why.
Please use this page as a starting place.
We need an overall description of our project at the overview level as well as the subsections and phases of implementation.

Counting Permutations
Improving Oligo Assembler We adapted the lancelator (http://gcat.davidson.edu/IGEM06/oligo.html), a program created by Lance Harden as a part of the 2006 iGem team, so that it would execute faster and can handle longer sequences. The old program could only handle sequences of 300 bp or shorter. Also, the more oligos the program broke the sequence into, the longer it took to run, and for 8 or more the run time was simply unreasonable. However, for the sequences it could handle it always finds the optimal oligos to use. Our program allows the user to enter a sequence of any length, and the length does not significantly effect runtime. In addition, we added extra features such as checking for and removing BioBrick restriction sites and adding BioBrick primers. While our program does not always find the optimal oligos, it still does very well which is an acceptable compromise because the runtime is improved so dramatically.

Note: All above segments have been optimized and deoptimized using the online Optimizer program.
To create the optimized and deoptimized segments of the Tet A gene we used the sequence that the Optimizer program gave us and put it into the Lancelator a program created by Lance Harden as part of the 2006 iGEM team. At this time we have ordered Oligo parts for segments 1 and 2 of the Tet A gene. The Oligos that were ordered can be seen below.
