You are a pancreatic cancer researcher designing a molecular beacon approach to detect a single nucleotide dominant mutation that indicates oncogene activation within a pancreatic tissue. You design the molecular beacon to hybridize to the single nucleotide mutation. You are sampling pancreatic tissue biopsies from patients to detect if they have acquired the oncogene mutation. How do you know if the mutation is present in the cells sampled?  Choose the most valid response.
