Following statements are regarding to proteins which involve actin filament assembly.
A. To nucleate the assembly of branched actin, Arp2/3 needs to be activated by interacting with a nucleation promoting factor (NPF), in addition to associating with the side of a pre-existing actin filament.
B. The NPF WASp is inactive due to an intramolecular interaction that masks the WCA domain.
C. Two NPFs each bind an actin subunit at their WH2 domains, and together, they activate the Arp2/3 complex through its interaction with their connector and acidic domains.
D. The NPF WASp is activated by a coincidence detection mechanism by which intramolecular interaction in WASp is relieved, allowing the W domain to bind actin and the acidic A domain to activate the Arp2/3 complex.
Which of the following statements represents regulation of the Arp2/3 complex by NPF?

One chromosome in a plant has the sequence A B C D E F, and another has the sequence M N O P Q R. A reciprocal translocation between these chromosomes produced the following arrangement: A B C P Q R on one chromosome and M N O D E F on the other. If an individual is heterozygous for this translocation, the consequence in meiosis will be as follows:
A. The two normal chromosomes and-two translocated chromosomes pair separately
B. Half of gametes produced from this meiosis are non-viable as they have deletions and duplications
C. In one of the cross configurations called "horizontal segregation" all gametes having normal or translocated chromosomes will not survive
D. The gametes having normal chromosomes only survive while all gametes having translocated chromosomes are non-viable, hence the translocations are used as crossover suppressors
Which of the following combinations best describes the meiotic consequences for the translocation described above?
