Question

What piece of equipment will you use to detect the actual location of DNA in the gel?

Options:
a) Pipette
b) Centrifuge
c) UV Transilluminator
d) Incubator

Answer 1

A UV Transilluminator is used to visualize DNA fragments in a gel by exposing the fluorescent dye-stained DNA to ultraviolet light, making it glow.

Step-by-step explanation:

To detect the actual location of DNA in the gel after electrophoresis, you would use a UV Transilluminator. This equipment shines ultraviolet light onto the gel, causing the fluorescent dye that is bound to the DNA fragments to glow. This allows for the visualization of DNA fragments following gel electrophoresis. In the context of molecular biology techniques, after DNA is stained with a fluorescent dye, the UV Transilluminator is crucial for observing the distinct bands that represent different fragments of DNA.
