Q1. Several eukaryotic mRNA’s, but not prokaryotic mRNA’s, contain introns. Illustrate how these sequences are removed throughout the production of mature mRNA.

Q2. Diplomonads, such as Giardia contain two haploid nuclei per trophozoite. Thus, During the G1 phase of the cell cycle, there should be a total of how several unreplicated chromosomes per trophozoite, and throughout the G2 phase, how many replicated chromosomes per trophozoite?
