Week 8 - Double-Cut-and-Join distance

About the end-capping phase (prior to DCJ steps), consider the following statements:

I - AA and BB paths are treated the same way when closed into cycles, with no arbitrary choices.
II - Before caps are incorporated into cycles, chromosomes are concatenated and additional operations made to prevent hurdles.
III - The expanded menu of end-capping operations avoid the need for extra precautions and saves running time to an O(n) complexity.

Select the alternative with all the correct statements and no others:
a. I.
b. II.
c. I and III.
d. II and III.
e. None of the above.
