Why are Short Tandem Repeats (STR's) important to DNA fingerprinting?
2 points
O
STR's are found in RNA so they are easier to isolate and examine than DNA
STR's are the same for everyone so they serve as a "baseline" for comparison
the STR's repeat different numbers of time in different people, creating bands of
different lengths
the STR's in different people code for different proteins, which can be analyzed on a
gel
