According to the article by Anne Bergeron, A Very Presentation Elementary Theory of Hannenhalli-Pevzner, 2005, which of the alternatives below DON'T represents the result of a reversal which minimizes the resulting score when applied at p = (1 6 4 -3 -5 2 7 -8)? 

     a) (4 5 6 1 -2 -3 -8 7)
     b) (2 1 6 4 -3 -5 -8 -7)     c) (1 -2 -3 -5 -4 -6 -8 7)
     d) (1 3 2 -4 -5 -6 -8 7)
     e) None of the above.

What is the result of applying the signed reversal ρ (B, D) in the circular genome π = (ABCD) (D -B -C -A)?

1. ρπ = (B C -A -D) (D A -C -B)
2. ρπ = (A B C D) (-D -C -B -A)
3. ρπ = (B C -D -A) (-C -B A D)
4. ρπ = (-D -C -B A) (-A B C D)
5. None of the above.
