Question
Fragments of DNA formed after treatment with endonucleases are separated by the technique of _______
Solution
The fragments of DNA formed after treatment with endonucleases are separated by the technique of Gel Electrophoresis.
Here are the steps:
-
DNA samples are prepared: The DNA is cut into fragments using restriction enzymes (endonucleases).
-
Loading the DNA into the gel: The DNA fragments are loaded into wells in the gel.
-
Applying an electric current: The gel is placed in a buffer solution, and an electric current is applied. DNA is negatively charged, so it moves towards the positive electrode.
-
Separation of DNA fragments: Smaller DNA fragments move faster and therefore travel further than larger ones.
-
Visualization: After the electrophoresis is complete, the DNA is stained to make it visible. The DNA fragments appear as bands on the gel. Each band represents a specific size of DNA fragment.
