Which one of the following statement is not true regarding gel electrophoresis technique?

  1. A
    The process of extraction of separated DNA strands from gel is called elution.
  2. B
    The separated DNA fragments are stained by using ethidium bromide.
  3. C
    The presence of chromogenic substrate gives blue coloured DNA bands on the gel.
  4. D
    Bright orange coloured bands of DNA can be observed in the gel when exposed to UV light.
