Question

The correct order for procedures profiling DNA is
A. DNA isolation PCR amplification Restricted enzyme Electrophoresis

B. DNA isolation Restrictive enzyme PCR amplification Electrophoresis

C. DNA isolation PCR amplification Electrophoresis Restricted enzyme

Answer 1

Answer:

A

Explanation:

First, you need to isolate the DNA from the subjects sample. Second, you need to amplify that DNA with PCR in order to be able to see enough DNA during gel electrophoresis at the end. Third, restriction enzymes are used in order to cut the DNA at specific sites. Fourth, you separate these small fragments using gel electrophoresis. The gel will give you a visual indication of all the fragments present in the subjects sample and thus help you profile the subjects DNA.
