What does the presence of multiple bands in the R- lane suggest?

• A. Two or more bands indicate multiple conformations.
• B. A single band indicates multiple conformations.
• C. No bands indicate multiple conformations.
• D. The number of bands is unrelated to conformations.

Answer: (A)

Multiple bands appear when the sample contains more than one form that migrates differently in the gel. In electrophoresis, molecules move based on size, charge, and shape; if the same molecule adopts different conformations, those forms can separate and show up as distinct bands. So a pattern with two or more bands in the R- lane indicates there are multiple conformations or structural forms present. A single band would mean one predominant form, while no bands would suggest no detectable product. The key idea is that bands reflect distinct species or conformations rather than a single uniform form.
