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.

The processes by which the three ectodermal regions are made physically and functionally distinct from one another is called neurulation. Following statements are regarding to the mechanism of neurulation.

A. The specification of the ectoderm is accomplished during gastrulation, primarily by regulating the levels of BMP experienced by the ectodermal cells.

B. High levels of BMP specify the cells to become neural plate.

C. Very low levels specify the cells to become epidermis.

D. Intermediate levels effect the formation of the neural crest cells.
