How does the action and mutagenic effect of 5-Bromouracil differ from that of nitrous acid? explain.

What is a protease enzyme? Why would we treat the strawberry extract with a protease in an extraction where the DNA needed to be subsequently analyzed?

Why are structural analogs of sugar molecules (such as Oseltamivir and zanamivir) effective in treatment of influenza-virus infection?

Given the following diagram of how protein AWESOME1 binds to it's target DNA, describe the potential effects of each of the 5 mutations shown below. The wild-type sequence of a helix #1 is also shown in the blue box, and all the mutations are in helix #1 (see numbers for identifying particular residues). a helix #1 R(1)-V-I-L-Y-F-W-I-M-Y-F-S-H-Y-W-R(16) #1 Predict the consequence of the following mutations: 1) Arg(1) to Glu 2) Arg(1) to Ala 3) Phe(6) to lle 4) Trp(7) to Phe 5) Met(9) to Pro in
