- Which of the following is NOT a true statement? (Check all that apply) A Prior to migration, all neural crest cells undergo EMT. B) Prior to migration, trunk neural crest cells undergo MET. C) All neural crest cells differentiate into their final derivatives at the site of their induction. D Neural crest cells are functionally equivalent to multipotent stem cells. E) The neural crest is specified where Wnt induces BMP and is then turn off. F The cranial neural crest contributes to the development of the tooth. G) All neural crest cells migrate dorsally from their induction site. H) Early migrating trunk neural crest cells are specified to become melanoblasts. O Ventrally migrating trunk neural crest cells that are responsive to Wnt and NT3 will become glial cells if they express Notch. Cranial neural crest cells all migrate ventrally from their site of specification.Explain how the presence of Notonecta chemical cues affects gene expression in the Daphniaa. Explain how you could use worms transformedwith myo-2::GFP to find mutations that disrupt thestructure of the pharynx. How would the presenceof the transgene facilitate the mutant screen?b. Nematodes homozygous for loss-of-function mutations in a gene called pha-4 have no detectablepharyngeal structures. How could you use myo2::GFP to determine if pha-4 is a master regulatory gene that directs development of the pharynxin a manner similar to the way Pax-6/eyeless controls eye development?

NOT HW just trying to get a better understanding on what this experiment is about. To produce mice that are deficient for RAC1 in macrophages, female C57BL/6 mice homozygously expressing the floxed Rac1 gene (Rac1fl/fl) [6] were crossbred with male mice homozygously expressing Cre under the monocyte-specific lysozyme M promoter (LC) [12]. Mice were genotyped for Rac1 deficiency as previously described
