Answer #1

Valarie's tumor DNA sample has fewer bands than the peripheral blood since her blood has DNA bands that contain both normal and mutant alleles.

Control lane provides us a method of controlling the experiment without altering the data in abnormal ways.

Yes, a physician can proceed with diagnosis based on molecular biological data since it provides viewing genes and how they might affect the patient. It also helps in determining the correct treatment to be provided.
