In the Southern blot technique, which of the following is NOT required?
A) restriction enzyme digestion of DNA
B) electrophoresis to separate fragments
C) addition of heat- stable DNA polymerase to amplify DNA
D) addition of a labeled probe to identify the gene of interest
E) transfer of DNA to nitrocellulose

Question

Quizplus · Accepted Answer

The addition of heat-stable DNA polymerase to amplify DNA is not required in Southern blotting. Instead, the technique utilizes restriction enzymes to digest DNA, electrophoresis to separate fragments, transfer of the DNA to nitrocellulose, and addition of a labeled probe to identify the gene of interest.
