Figure 1From: Gene cassette transcription in a large integron-associated arrayAttC PCR primer design. Primers YB3 and YB4 are shown aligned with a typical attC sequence (the cassette 19-20 junction in this case) from the Vibrio sp. DAT722 array. The dotted line indicates the attC recombination site. YB3 is shown reversed for clarity.Back to article page
