The band on the gel are correct but there is a lot od DNA on the top of the gel and the secnd band is very weak. Morover, the sequence we ordered for otsB is wrong, so we need to correct it by PCR. So we will ordered primers and we’ll send to sequence after the PCR. For otsA, we’ll make an other transformation to select only one pure clone
