the geologic processes seen on earth today are the same processes that took place in the past. which principle explains this idea?

a) principle of uniformitarianism

b) principle of superposition

c) principle of horizontal originality

d) principle of faunal succession

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."

i'll try what topic lol
