I was expecting only ~110bps amplicon in my sample, but I see a very broad band. Attached is the result. 2 and 4 only contain the template, no primers. Also, I think my intensity is kind of low.
I want to use two promoters to express two gRNA in a single plasmid and wish them to have same number(i.e. two promoter with nearly same strength). I am not sure whether I should insert a...
