Figure 21-16 in Watson's textbook (below) describes an experiment to test whether the 3' untranslated region of the bicoid mRNA contains a base sequence that causes this RNA to be localized at the anterior pole of the Drosophila egg. A. To test this hypothesis, the investigators engineered a hybrid the normal oskar and bicoid" mRNAs. In terms of DNA cloning, 5UTR3 explain in general how you could bicoid mRNA synthesize an mRNA that fuses the 5' end of the bicoid mRNA to the 3' end of the oskar mRNA UTR oskar mRNA bicoid oskar mRNA ole cells wi oskar mRNA B. Although not stated in the figure, the investigators injected their fusion oskarlbicoid mRNA into newly laid Drosophila eggs to see whether it became localized. Given the data shown in this figure, why did the investigators conclude that the fusion mRNA was localized to the anterior pole of the egg?
