The molecule that provides energy for cellular processes is
a. atp.
c. dna.
b. rna.
d. protein.

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."

the correct answer is:

a population changes in response to a change in the environment.
