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?We have spent a lot of time comparing channelrhodopsin (which is found in Chlamydomonas) with rhodopsin (which is found in humans). What about these two photoreceptors is correct? A. The opsin proteins are homologous and serve as ion channels that transport Ca2+ ions. B. The opsin proteins aren’t homologous, but both species have homologous enzymes involved in retinal synthesis. C. The opsin proteins aren’t homologous, but they both interact with G proteins, that do share a common ancestry. D. The opsin proteins are homologous, they just fold into very different native conformations.Yeast cells are eukaryotes, and they require a functional secretory pathway to grow and to maintain cellular organization. But surprisingly, when SRP is removed from yeast cells by deleting the relevant genes, the cells are still alive (although they grow slowly). a) How can yeast survive without SRP?
