What happens during interphase? a. the cell prepares for mitosis. b. the cell splits apart. c. the sister chromatids separate. d. the gametes form?

a. the cell prepares for mitosis.

Explanation:

Interphase is the period preceding any cell division, being of intense metabolic activity. During this period, there is the preparation for cell division (mitosis or meiosis), which involves the duplication of chromatin, the material responsible for controlling cell activity. All information existing throughout the DNA molecule is passed to the copy as if it were a photographic copy of the original molecule. Before long, each cell formed from the split will receive an exact copy of each chromosome of the split cell.

The two copies of each chromosome remain together for a time, joined by the common centromere, constituting two chromotids of the same chromosome. In interphase, the centrioles also duplicate.

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."

that is wrong, its not thymus.
