No, the agarose gel is just a polysaccharide.

When is DNA cut during electrophoresis?
Electrophoresis technique is not designed to cut DNA molecule. When DNA is analyzed by electrophoresis to determine its molecular mass, the molecular biology engineer usualy digests the DNA molecule, before the electrophoresis, with specific enzymes called "restriction enzymes" in order to obtain fragments of diverse molecular weights that can be seen as bands in electrophoresis gels.
Why native gel electrophoresis can be used for determining the molecular weight of proteins?
No! native gels are used to run the proteins in native form, this will tell about the protein's mulimeric nature (ie.monomer or dimer or tetramer etc..).
What is the purpose of gel electrophoresis?
The buffer is the medium through which the current flows. In the electrophoresis chamber, the anode and cathode are separated and the gel is placed between them. In order to close the circuit and generate the voltage which causes the migration, the entire chamber is filled with a conductive buffer. It is actually possible to perform electrophoresis without a buffer; however this requires a specially made electrophoresis chamber. In these chambers the electrodes actually contact the top and bottom of the gel eliminating the need for a conductive buffer to close the circuit.SDS PAGE electrophoresis uses buffer not primarily as a conductor but for holding a desired pH, dissipating heat and providing SDS in excess in the case of denaturing gels. A gel would run without a buffer as the gel itself is a conductor but the currents involved would heat it to the point of decomposition. Also the volume of liquid in a gel does not allow for an adequate pH buffering system. Holding a pH is extremely important for reproducibility especially in native gels as the pH can change the charge on the peptide. It is true some gels do not require buffer but these are rare cases like isoelectric focusing.the primary application of the buffer would be to conduct electricity,to form a closed circuit
What is a technique for sorting DNA fragments by length?
it is called " electrophoresis"
Can a gel electrophoresis be performed both horizonnally and vertically?
yes for example 2D gel electrophoresis
What is a gel electrophoresis is not used for?
anal lube is what the gels used for
