NEETBiologyBiotechnology Principles and ProcessesMCQ+4 / −1
DNA fragments generated by the restriction endonucleases in a chemical reaction can be separated by :
  1. A
    Polymerase chain reaction
  2. B
    Restriction mapping
  3. C
    Electrophoresis
  4. D
    Centrifugation
View written solutionFree

Correct answer: C

DNA fragments generated by restriction endonucleases in a chemical reaction can be separated by gel electrophoresis. Since DNA fragments are negatively charged molecules they can be separated by forcing them to move towards the anode under an electric field through a medium/matrix. The DNA fragments separate according to their size through sieving effect provided by matrix.
