In a mixture, DNA fragments are seperated by:
Restriction digestion
Electrophoresis
Polymerase chain reaction
Bioprocess engineering
After the cutting of DNA by restriction enzymes, fragments of DNA are formed. These fragments can be separated by a technique called gel electrophoresis.
Electrophoresis is a technique of separation of charged molecules under the influence of electric field through a medium/ matrix.The most commonly used matrix is Agarose.
