The data table below shows the presence or absence of DNA in four different cell organelles. Information in the table suggests that DNA functions
A. within cytoplasm and outside of the cell membrane
B. both inside and outside of the nucleus
C. only within energy-releasing structures
D. within cell vacuoles

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?
