Answer:
c)polymerase chain reaction (PCR).
Explanation:
Because the paleontologist recovered only a bit of tissue and it is very old, it is very likely that the DNA in the sample is very small and part of it is degraded. Anyway, the paleontologist must first amplify the DNA sample to obtain many identical copies of the specific region of the DNA they want to compare. the above is done through a polymerase chain reaction (PCR).
1. Calcium carbonate minerals are the building blocks for the skeletons and shells of mini marine organisms. It is important to ocean creatures because they make their shells out of this material. Examples of animal products that are primarily of calcium carbonate include seashells, egg shells, pearls, and notably coral
