Which is an example of complementary base pairing in dna? a. thymine pairing with cytosine b. guanine pairing with cytosine c. adenine pairing with cytosine d. uracil pairing with cytosine

its always A-T and C-G, so B guanine and cytosine

answer; i believe the answer is hydraulic action;

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."
