In order to identify a specific restriction fragment using a probe, what must be done?

A. The probe must be hybridized with the fragment.


B. The fragments must be separated by electrophoresis.


C. The fragments must be treated with heat or chemicals to separate the strands of the double helix.





D. The fragments must be separated by electrophoresis or must be treated with heat or chemicals to separate the strands of the double helix





E. The fragments must be separated by electrophoresis, treated with heat or chemicals to separate the strands of the double helix, or the probe must be hybridized with the fragment|||I would choose answer E, but shouldn't the "or" after "double helix" be an "and"?
