Biology Question

What would be the most likely effect of inhibiting the translation of hunchback mRNA throughout a Drosophila embryo?

Describe the formation steps of the primary axis that first occurs during development in Drosophila by explaining each molecule.

Lateral inhibition and induction are key processes in embryonic development. Discuss two different signalling pathways involved in these processes,

Discuss the morphological differences between the parasegments and segments of Drosophila. Discuss the evidence, providing specific examples, that suggests the parasegments of the embryo are the subdivisions for the organization of gene expression.

“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”. Discuss whether this statement is correct.

Describe the expression pattern of the Drosophila geneeve in the early embryo.

Discuss how the anterior portion of the anteroposterior axis is established in Drosophila. What aspects of oogenesis are critical in establishing this axis? What do you think would happen if the bicoid mRNA was not trapped at the anterior end but instead diffused freely throughout the oocyte?

Explain please

provide one example from the Drosophila AP toolkit for "Toolkit genes can be classified according to the phenotypes caused by their mutation. 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."
