Question

How to detect radioactive DNA?

Answer 1

Radioactive DNA:

1. Scintillation counting, which involves blending tiny amounts of radioactive DNA with the scintillation fluid, can be used to identify radioactive DNA.
2. Beta particles are released during the radioactive isotope's decay. When the beta particle excites the scintillation fluid, a flash of light results.
3. A photocell used by the scintillation counter counts the light flashes over a predetermined period to identify the flashes of light.
4. By comparing the concentrations of radioactive DNA to a list of known values, the concentrations can be determined.
