Question

27. Separation and isolation of DNA
fragments can be done by a technique
called gel electrophoresis. This technique
separates DNA on the basis of
a) size of DNA fragments
O b) charge present on DNA fragment
O c) bases present in DNA fragment
O d) none of the above​

Answer 1

Answer:

Please mark me brainliest

Explanation:

The technique used for separation of DNA fragments is called gel electrophoresis. The technique is based on the principle that - when a charged molecule is placed in an electric field they move towards the positive or negative side according to their charge. When the electric field is applied in DNA fragments being negatively charged,move through the gel towards the anode and gets separated.
