Scientists use light from various wavelengths on the
electromagnetic spectrum in many different ways.
Different types of light are useful for different types of
experiments. Which of the following correctly identifies
a comparison of two different types of waves?
A. Gamma rays usually have a lower energy than
visible light waves.
B. Infrared waves have a longer wavelength than
ultraviolet light waves.
C. Microwaves have a higher frequency than X-rays.
D. The rainbow of visible light has different
wavelengths- with red light as the smallest
wavelength and purple (violet) light as the longest
wavelength.

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?
