In Molecular Biology All of the Following Methods Can Detect

Question

In molecular biology all of the following methods can detect small traces of radioactivity except
A)liquid scintillation counting.
B)autoradiography.
C)x-ray film.
D)phosphorimaging.
E)spectrophotometry.

Accepted Answer

Spectrophotometry is not a method used for detecting radioactivity. It is a technique used to measure the absorbance or transmission of light by a sample in order to quantify the amount of a specific compound present. The other methods listed all involve detecting radioactivity in some way.
