∙ 13y agogel electrophoresis separates DNA fragments according to size. Samples containing a mixture of DNA molecules of different sizes are loaded on to the gel. When an electric current is applied DNA moves towards the positive electrode since DNA is negatively charged.
The place in which the sample is loaded (sample wells) is called the origin. Larger molecular weight fragments move slowly through the gel under the influence of the electric current and are seen closer to the origin. Smaller molecular weight fragments however, more further away from the origin since they move through the gel faster (because of their smaller size)

∙ 9y agoGel electrophoresis separate DNA fragments on the basis of charge and molecular weights of the DNA fragment. Since DNA is negatively charged molecule it tends to move toward anode or positive electrode when there is an electric current is applied. The migration of DNA is also proportional to the size, 100 nucleotide DNA moves two times faster than 200 nucleotide DNA.

∙ 14y agoYes, one can separate DNA molecules by charge, size, and shape using agarose gel electrophoresis.

∙ 13y agoMoves them. The fragments move due to the charge they contain. The rate at which they move is a function of the size of the fragment. Smaller fragments move more quickly.

∙ 11y agoYes. The smallest fragments go the farthest.

DNA fragments can be separated and analyzed by?
Pulse field gel electrophoresis is used to separate DNA fragments by their size.
What is used to sort DNA into different lenghts?
Gel Electrophoresis
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
Can DNA sequence be cut into smaller fragments by gel electrophoresis?
electrophoresis takes segments of DNA that are already broken up and aligns them by length with an electric current. It doesn't cut the DNA.Added:No, they must be cut into smaller pieces by restriction enzymes ( HINDI, for instance ) before they are run in the gel.
Properties of DNA fragments which allow them to be separated from each other during gel electrophoresis?
They are negatively charged and are of different sizes
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.
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"
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
DNA fragments can be separated and analyzed by?
Pulse field gel electrophoresis is used to separate DNA fragments by their size.
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 are the scientific uses for polyacrylamide?
it is used in gel electrophoresis.....for the separation of DNA fragments
What holds the DNA sample during electrophoresis?
DNA samples are within the gel matrix during electrophoresis. DNA moves at differtent rates through the pores of the gel depending on how long the fragments are. DNA is held by the gel itself.
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
What are 3 charcteristics that allow gel electrophoresis to work?
The following allow gel electrophoresis to workDifferent sized DNA fragmentsThe migration of DNA under the influence of an electric field in the gel toward the positive electrodeThe different speeds of migration of the DNA fragments - larger fragments moving slower than smaller fragments
After DNA is cut with a restriction enzymes how is the mixture of DNA fragments sorted?
Through the process of gel electrophoresis.
