There is a specific density of gel used in the electrophoresis. The DNA is placed in a well, and then electrical charge is used to pull the DNA through the gel. Because spliced DNA is slightly charged, it begins to move through the gel. The density of the gel causes the larger pieces to go slower than the smaller pieces. Think of it like this: what is a faster way to get through rush hour traffic? Using a bicycle to pedal through all the cars, or being stuck in a taxi cab. The taxi cab, which is larger, moves slower through the traffic. The bicycle which is smaller, moves quicker.

What is used to separate DNA fragments by size?
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.
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
Where do you get the DNA fragments for Gel electrophoresis?
The DNA fragments comes from the method of DNA isolation.
How are DNA fragments separated on DNA fingerprinting?
Gel electrophoresis
What is a technique for sorting DNA fragments by length?
it is called " electrophoresis"

Are restriction enzymes used in gel electrophoresis?
For DNA gel electrophoresis, yes. Once the DNA is cut up into different-sized fragments, they can be electrophoresed to separate bands.
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.
Where do you get the DNA fragments for Gel electrophoresis?
The DNA fragments comes from the method of DNA isolation.
How are DNA fragments separated on DNA fingerprinting?
Gel electrophoresis
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.
What is a technique for sorting DNA fragments by length?
it is called " electrophoresis"
Process that restriction fragments of DNA are separated from each other by the use of electricity?
The process is referred to as gel electrophoresis. This is an analytical process where DNA fragments can be separated based on size within a gel under the influence of an electric field
What explains the role of gel electrophoresis in forensic science?
It is a special technique used to separate and identify DNA fragments.
How does DNA and gel electrophoresis relate?
Gel electrophoresis separates an individual's DNA fragments from one another according to size. An electric current repels a mixture of the negatively-charged DNA fragments through microscopic pores in the gel from the negative to the positive electrode. Upon completion, the separated fragments of DNA can be visualized as a ladder of small bands in the gel by staining with a methylene blue dye solution or smaller DNA segments move more easily through the gel.
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
