Analysis of a homotetrameric protein and a double stranded DNA (that had been incubated in standard buffer) on native gels revealed that they migrated true to their physical states (tetrameric nature of the protein and double stranded nature of the DNA). Following hypotheses were made for the effect of adding high salt to the incubation mix and subsequent analysis on native gels: A. The protein would migrate as a homotetramer and DNA in double stranded form. B. The protein would migrate as a monomer but DNA in double stranded form. C. The protein would migrate as a homotetramer but the DNA in single stranded form. D. The protein would migrate as a monomer and the DNA in single stranded form. Which of the following combination of hypotheses is most likely?
- 1A and D
- 2C and D
- 3B and C
- 4A and B✓
