Why is gel electrophoresis a necessary step, during Sanger Sequencing? A-
B- The nucleotide base sequence of the template strand is determined by the sequential and direct
reading of the bands developed in the four lanes of the gel, produced through electrophoresis
C- The nucleotide base sequence of the replicated strand is determined by the sequential and direct
reading of the bands developed in the four lanes of the gel, produced through electrophoresis
D- To determine the molecular weight of each fragment
E- To find mutations in the replicated strand
