Design Notes

IS6110 has normally two open reading frames. OrfA (327 bp) and orfB (927 bp) are consecutive ORFs partially overlapping in the relative translational reading frames 0 and −1, respectively. For the purposes of our project, we designed primers for orfB only. To ensure maximum biosafety, we cloned only a non-functional fragment of the part into E. coli DH5-alpha via TA cloning. This guarantees safety for the environment for potential GM DNA transpositions, as well as enough DNA material for us to work on our project.

IS6110's complete CDS is depicted with a green line and the non-functional fragment we used for our experiments (987 bp) is depicted with an orange line:
