TEIIB O contacts the DNA at the BRE will bind only if TFIID is bound O is the third factor to bind the complex O all of the above

The pathway for arginine biosynthesis in Neurospora crassa involves several enzymes that produce a series of intermediates as shown. O O O O ornithine citrulline ARG-E arginosuccinate arginine N-acetylornithine arginine You did a cross between ARG-E ARG-H* and ARG-E* ARG-H¯¯ Neurospora strains and identified an Arg- strain from an NPD tetrad. (Assume that Neurospora forms tetrads in the same way yeast do.) Which compound would rescue growth of this Arg- spore? N-aceltylornithine ARG-F ornithine citrulline ARG-G ARG-H → argininosuccinate

What is an "orphaned response regulator?" O A response regulator that is nonfunctional because it has no partner histidine kinase O A response regulator whose partner histidine kinase is unknown O A fusion of a response regulator and a histidine kinase to create a single functional protein O A response regulator whose partner histidine kinase is not placed side by side with it in the genome
