How can the 2D gels identify the DNA intermediates associated with a replication origin? Choose combination of correct statements

A. Y-shaped molecule that has three equal length arms will migrate the most slowly of all such molecules derived from a particular DNA fragment

B. A Y-shaped molecule with two very short replicated arms and a large replicated region will migrate very similarly to the unreplicated version of the same DNA fragment. 

C. Y-shaped molecule that results from the almost completely replicated fragment is similar in shape to a linear molecule two times the size of the unreplicated fragment.
