Question

which indicator is typically placed into the DNA samples to visualize the bands in the gels after gel electrophoresis is performed?

Answer 1

Fluorescent dye

Step-by-step explanation:

After electrophoresis, the DNA is then visualized by staining the gel with a fluorescent dye.

This dye binds to the DNA after which it is placed on an ultraviolet transilluminator. This shows the stained DNA as bright bands.
