d. Anaphase

telophase

Explanation:

Telopahse is the last phase of mitosis. The chromosomes uncoil then a membrane forms around them and the one cell splits into two cells.

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."
