− | <h2>Results:</h2>
| + | |
− | <p> While GFP and the Gibson kit positive control had colonies, the gRNA Gibson product (Tet) and positive transformation control (Cam) did not yield colonies.</p>
| + | |
− | <p>The gRNA Gibson has falied grow the past two times we transformed it, so we’re suspicious that it might not be a problem with the Gibson assembly, because the Gibson control has grown on Amp.</p>
