The whole process can be divided into the following steps:
==== Conserved Sequence Analysis ====
 
 
We first extracted all conserved regions from the NIH HIV-1 Reference Genome. In this step, we found around 10 alternatives for the next process. Here all screening processes are done in a per-strain basis because of the high mutability of the HIV-1 virus.

Designing the Sequence

We used a method derived from the method described in the paper by Feng Zhang[http://www.nature.com/nbt/journal/v31/n9/abs/nbt.2647.html ZhangFgRNA].

The whole process can be divided into the following steps:
