A bacteriophage contains a single stranded DNA molecule. This DNA contains 19% adenine, 23% thymine, 45% guanine, and 13% cytosine. An RNA molecule complementary to this DNA is made. In this newly synthesized RNA strand, how much of each base would be found?

Assume that you are interested in separating short (200-400 bp) dna molecules from a pool of longer molecules in the 10,000-20,000 nucleotide range. you have two recipes for making your polyacrylamide gels: one recipe uses 1.5 percent agarose and would be considered a “hard gel,” while the other uses 0.5 percent agarose and would be considered a loose gel. which gel should you use to separate the short (200-400 bp) dna molecules from a pool of longer molecules in the 10,000-20,000 nucleotide range?
