Agarose gel electrophoresis is the most effective way of separating DNA fragments of varying sizes ranging from 100 bp to 25 kb 1Agarose is isolated from the seaweed genera Gelidium and Gracilaria and consists of repeated agarobiose L- and D-galactose subunits 2During gelation agarose polymers associate non-covalently and form a network of.

Large DNA molecules move slower and can be observed at the top of the gel whereas smaller DNA fragments move faster and are seen at the bottom of the gel. What is the process of gel electrophoresis. What explanation best describes the role of gel wells.

The DNA is loaded into wells formed by combs in the agarose gel buffer is added then an electric current is applied and the DNA migrates to the bottom How are the DNA fragments filtered in the agarose gel during gel electrophoresis. _____ causes DNA fragments to migrate. In agarose gel electrophoresis proteins are loaded in the middle of the well.

Its purpose is to line up the protein sample that is loaded on the gek so that they can be entered in the resolving gel at the same time. Scientists can determine the size of DNA fragments through a process known as gel electrophoresis. The gel electrophoresis equipment has two poles positive pole and negative pole at the each end.
