Description : How does gel electrophoresis separate DNA fragments?
Last Answer : There is a specific density of gel used in the electrophoresis.The DNA is placed in a well, and then electrical charge is used topull the DNA through the gel. Because spliced DNA is ... taxi cab, which is larger, movesslower through the traffic. The bicycle which is smaller, movesquicker.
Description : Why can gel electrophoresis separate dna fragments?
Last Answer : Electrophoresis enables you to distinguish DNA fragments of different lengths. DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively ... marker, you can work out the approximate length of the DNA fragments in the samples.
