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 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
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

DNA fragments can be separated and analyzed by?
Pulse field gel electrophoresis is used to separate DNA fragments by their size.
Why are D1S80 fragments separated by gel electophoresis?
Fragments are separated by gel electrophoresis because of their differing sizes. DNA is negatively charged, so will migrate through the gel towards the positive electrode. The smaller fragments are able to move through the gel more quickly than the larger fragments - which means they separate based on their size.
During gel electrophoresis do long or short fragments travel more quickly toward the positive pole?
Short fragments are able to move faster (longer = heavier = slower).
What is the function of buffer in the gel electrophoresis?
TBE buffer in gel electrophoresis is used to maintain pH of te solution and prevents the denaturation of smale fragments of DNA.
What are the scientific uses for polyacrylamide?
it is used in gel electrophoresis.....for the separation of 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.
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.
