HELP! A question for my online exam for oceans I’m stuck on is this…

Some scientists think the sea floor is one of the most interesting and amazing areas on Earth. Why do you think they have this opinion?

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."

voluntary muscles are controlled by the cerebellum.

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
