Electrophoresis. Restriction enzymes are used to cut DNA into fragments. Solutions containing these fragments are placed on the surface of a gel to which an electric current is applied. The electric current causes the DNA fragments to move through the gel. Because smaller fragments move more quickly than larger ones, this process separates the fragments according to size.

Can electrolysis be used to separate DNA fragments?
Yep!
What procedure is used to separate and analyze DNA fragments by placing a mixture of DNA fragments at one end of a porous gel and supplying an electrical voltage to the gel?
agarose gel electrophoresis
Use of agrose in DNA isolation?
Agarose is not used in DNA isolation. Agarose is used to prepare a gel in which DNA fragments can be separated based on size
What causes the bands on your DNA gels?
During gel electrophoresis, the DNA moves along the agarose gel to the positive side of the box, and after a certain amount of time, the smaller DNA fragments travel the farthest (because they have an easier time navigating the pores of the gel) and so on, leaving behind a series of bands comprised of similar-sized DNA fragments.
How does electrophoresis separate DNA based upon differences in size?
Electrophoresis is the motion of dispersed particles (like DNA fragments) relative to a fluid under the influence of a spatially uniform electric field. DNA electrophoresis is an analytical technique used to separate DNA fragments by size. DNA molecules which are to be analyzed are set upon a viscous medium, the gel, where an electric field forces the DNA to migrate toward the positive potential, the anode, due to the net negative charge of the phosphate backbone of the DNA chain. The separation of these fragments is accomplished by exploiting the mobilities with which different sized molecules are able to traverse the gel. Longer molecules migrate more slowly because they experience more drag within the gel. Because the size of the molecule affects its mobility, smaller fragments end up nearer to the anode than longer ones in a given period.
Can electrolysis be used to separate DNA fragments?
Yep!
Gel electrophorysis and GMO food?
Gel electrophoresis is a method for separation and analysis of macromolecules (DNA, RNA and proteins) and their fragments, based on their size and charge.The tool of DNA gel electrophoresis was developed in the 1970s. The process uses electricity to separate DNA fragments by size as they migrate through a gel matrix.It can be used to separate proteins that are used in genetically modified foods.
The technique used to analyze DNA directly results in?
separating DNA fragments on the basis of size
Explain how an agarose gel can separate DNA fragments of different lengths.?
The separation of DNA fragments is based on size. When a DNA sample is run in a gel (electrophoresis), the lighter fragments migrate faster than the heavier (longer) fragments under the influence of an electric current. At the and of the process, the shorter fragments are found at the terminal end of the gel and the longer fragments closer to the origin
What procedure is used to separate and analyze DNA fragments by placing a mixture of DNA fragments at one end of a porous gel and supplying an electrical voltage to the gel?
agarose gel electrophoresis
DNA fragments can be separated and analyzed by?
Pulse field gel electrophoresis is used to separate DNA fragments by their size.
Use of agrose in DNA isolation?
Agarose is not used in DNA isolation. Agarose is used to prepare a gel in which DNA fragments can be separated based on size
One function of gel electrophoresis is to?
To separate strands of DNA based on their size. Shorter strands will migrate more slowly than larger strands. ** Also because DNA is slightly negatively charged, it will move toward the positive end of the electrodes... this is why the current is used when running a gel. Short strand move further** than large ones due to the gel resistance.
What is the role of Ficol in DNA quantification?
Ficoll, basically polysucrose is used to prepare density gradients during centrifugation to separate DNA fragments.
What explains the role of gel electrophoresis in forensic science?
It is a special technique used to separate and identify DNA fragments.
What is a DNA size standard and why is it used in gel electrophoresis?
You may be referring to the DNA ladder used in gel electrophoresis. The ladder is a collection of DNA fragments of known size (e.g. 100, 500, 1000, 2000, 5000, 10000 base pairs) so that if it is loaded beside the samples, it can offer a 'ruler' that can be used to determine the size of the fragments in the samples.
What causes the bands on your DNA gels?
During gel electrophoresis, the DNA moves along the agarose gel to the positive side of the box, and after a certain amount of time, the smaller DNA fragments travel the farthest (because they have an easier time navigating the pores of the gel) and so on, leaving behind a series of bands comprised of similar-sized DNA fragments.
