The Following are Steps Used to Make DNA Fingerprints

Question

The following are steps used to make DNA fingerprints.What is the third step?
A)Collect DNA.
B)Digest with a restriction enzyme.
C)Perform electrophoresis.
D)Lyse cells.
E)Add stain.

Accepted Answer

The third step in making DNA fingerprints is to digest the DNA with a restriction enzyme. Restriction enzymes are enzymes that cut DNA at specific sequences of nucleotides. This step is necessary to create the DNA fragments that will be separated by electrophoresis.
