Gel electrophoresis separates DNA fragment on the basis of their size. In DNA fingerprinting or DNA typing given sample is cut up with restriction enzymes and run through electrophoresis and results are analyzed to check for DNA polymorphism between the given sample and a sample form suspect. In nutshell gel electrophoresis is boon for the people in forensics.

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 is the conclusion on the application of gel electrophoresis?
One of the Conclusion of electrophoresis is Visualization of the DNA size. Second is Sequencing the length of DNA of the body.
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 are the pros and cons of gel electrophoresis?
Pros: The detection of DNA, RNA and proteins can be done using gel electrophoresis. Gel electrophoresis does not require a large amount of starting material. Cons: difficult to extract samples for further analysis. Harmful materials.
Why is gel electrophoresis important?
To separate and analyze DNA fragments and protein fragments by weight. If you have digested some bacterial DNA, for instance, then you can tell by running the fragmented DNA in the gel whether you have digested the correct base length.
How do you make DNA fingerprint?
gel electrophoresis
Which process involving DNA creates a DNA pattern or fingerprint unique to an individual person?
DNA fingerprinting
A pattern produced from fragments of the DNA of a specific person?
Gel electrophoresis is the process that is used in DNA creates and pattern unique to an individual person. Each person has their own DNA patterns.
What is the pattern of dark bands on photographic film that is made when DNA fragments are separated by gel electrophoresis and tagged?

What are the common stains that is used after DNA electrophoresis?
Ethidium bromide and coomassie blue are some stains that can be used in DNA electrophoresis.
How is a DNA FINGERPRINT PRODUCES?
Selected fragments are used to produce a DNA fingerprint.
What is used to sort DNA into different lenghts?
Gel Electrophoresis
What method is used to make DNA fingerprints?
A method known as RFLP (restriction fragment length polymorphism) analysis can be used to make a DNA fingerprint.
A technique that can be used to compare the DNA of two or more plants is?
Gel electrophoresis
What is used to sort DNA into lengths?
Gel Electrophoresis
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.
