This week, I performed the second DNA extraction on the unknown Larrea Tridentata bacteria. I was unsatisfied with the results I obtained a couple of weeks ago because the NanoDrop DNA values were low (well, at least to me). Due to these results, I thought I had done something wrong. With this in mind, I was hoping to get higher amounts of DNA during this extraction. However, that was not the case because I practically had about the same amount of nucleic acid. After this extraction, nothing changed and I will be using these samples for PCR. Below is the nucleic acid graph and data table for this second extraction (Group B).
