1. In describing the timing of Drosophila development, researchers use AEL to mean âAfter egg layingâ, for example, 40 h AEL means 40 hours after egg laying. At 25o C, a fruit fly of 75 h AEL is at:
A. Embryonic stage
B. Larval stage
C. Pupal stage
2.The Green Fluorescent Protein (GFP) gene:
A. Is an endogenous gene that naturally existing in the Drosophila genome
B. Often exists as a transgene in the Drosophila genome, flies that bear a GFP gene is considered as transgenic flies
