You are working in a laboratory and create a new molecule. This new molecule is a large, non-charged molecule (a molecule without any charges). Based on what was covered, this molecule you created will most likely go through the cell membrane: a. via (or using) only carriers
b. via (or through) channels
c. via (or using) facilitated diffusion
d. via (or through) the membrane bilayer
e. via (or using) pinocytosis (because it is a large molecule)

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?
