Answer the following questions. a. What is the title of the first published paper explained the experiment and what is the name of the Author? b.

- Can I get a paragraph about the Repo protein that is used in Drosophila melangaster?Christiane Nüsslein-Volhard and her colleagues carried out several experiments in an attempt to understand what determines the anterior and posterior ends of a Drosophila larva (reviewed in C. NüssleinVolhard, H. G. Frohnhofer, and R. Lehmann. 1987. Science 238:1675– 1681). They isolated fruit flies with mutations in the bicoid gene (bcd−). These flies produced embryos that lacked a head and thorax. When they transplanted cytoplasm from the anterior end of an egg from a wild-type female into the anterior end of an egg from a mutant bicoid female, normal head and thorax development took place in the embryo. However, transplanting cytoplasm from the posterior end of an egg from a wild-type female into the anterior end of an egg from a bicoid femalehad no effect. Explain these results in regard to what you know about proteins that control the determination of the anterior–posterior axis.Compare and contrast the experimental advantages and disadvantages of Drosophila, C. elegans, mammals, and Arabidopsis.

Similar mutant phenotypes often reflect genes that function in a single developmental pathway. Distinct pathways exist for the generation of body axes, for example, and for the formation and identity of fields."“In the early Drosophila embryo, the establishment of different body regionor tissues along, on the one hand, the anteroposterior axis and, on theother, the dorsoventral axis are initiated by clues provided by the egg’smother; however the nature of those signals and the way in which theyoperate is completely different”.
