WebOnce enough copies of the sequence have been produced by PCR, electrophoresis is used to separate the fragments according to size. Each fragment passes by a laser which causes the fragments with fluorescent tags to glow with a specific colour. WebIn electrophoresis, consider the gel as a molecular sieve, a tightly woven mesh. Just like an ordinary sieve – say a coffee filter, it allows smaller particles to pass through easily, while the larger particles are left behind due to their bigger size.
