Question asked by Filo student

Cutting of DNA: Cutting of DNA into fragments is performed by restriction enzymes. This process is known as restriction enzyme digestion. Isolation of Desired DNA Fragments:

1. The desired DNA fragment can be isolated by a technique called gel electrophoresis.
2. In this technique, the DNA fragments are forced to move towards anode through a medium called agarose.
3. After that, DNA fragments are stained with ethidium bromide. When exposed to UV light, the resulting stained gel resembles bands of bright orange DNA.
