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

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

step-by-step explanation:

48 dollars divided by 200 beads equals .24 dollars a bead

.24 multiplied by 25 more beads equals 6 dollars as the total cost
