week 10

A genome underwent a operation that changed it as showed by the representations below:

Before:
π_adj = (-A B) (-B D) (-D C) (-C -F)

After:
π_adj = (-D C) (-C -F) (F A) (-A B) (-B D)

What operation happened?

a) Linear fission
b) Circularization
c) Reversal
d) Transposition
e) None of the above
