What process would allow a forensic scientist to sort dna by the length to use as a basis of comparison ? a southern blotting b gel electrophoresis c x-ray crystallography d polymerase chain reaction

The answer is Gel electrophoresis. This is the process that would allow a forensic scientist to sort DNA by the length to use as a basis of comparison.  Gel electrophoresis is a method for separation and analysis of macromolecules (DNA, RNA and proteins) and their fragments, based on their size and charge. In biochemistry and molecular biology it is used to separate a mixed population of DNA and RNA fragments by length, to estimate the size of DNA and RNA fragments or to separate proteins by charge
