Electrophoresis for nucleic acids (RNA and DNA) works by separating segments by their size. This is possible because RNA and DNA are negatively charged, so will move towards the positive charge applied to one end of the gel.
The different segments separate because small fragments of RNA or DNA are able to move more quickly through the gel than larger fragments.

What is a common name for gel electrophoresis?
Agarose gel electrophoresis.
What was used before gel electrophoresis?
Before gel electrophoresis, techniques like paper electrophoresis and agarose slab gel electrophoresis were used for separating and analyzing DNA or proteins. These methods were less efficient and had lower resolution compared to gel electrophoresis.
Can a gel electrophoresis be performed both horizonnally and vertically?
yes for example 2D gel electrophoresis
Where can one learn more on gel electrophoresis?
To learn more about gel electrophoresis, one can Google it. There is also a whole Wikipedia article dedicated to gel electrophoresis, and it happens to be quite informative.
When is DNA cut during electrophoresis?
Electrophoresis technique is not designed to cut DNA molecule. When DNA is analyzed by electrophoresis to determine its molecular mass, the molecular biology engineer usualy digests the DNA molecule, before the electrophoresis, with specific enzymes called "restriction enzymes" in order to obtain fragments of diverse molecular weights that can be seen as bands in electrophoresis gels.
What has the author A J Houtsmuller written?
A. J. Houtsmuller has written: 'Agarose-gel-electrophoresis of lipoproteins' -- subject(s): Blood protein electrophoresis, Electrophoresis, Gel electrophoresis, Lipoproteins
When was Electrophoresis - journal - created?
Electrophoresis - journal - was created in 1980.
What is a common name for gel electrophoresis?
Agarose gel electrophoresis.
How does gel electrophoresis work and what kind of information can you determine from gel electrophoresis?
Gel electrophoresis separates DNA or proteins based on size and charge by applying an electric field to move molecules through a gel matrix. Smaller molecules move faster and thus travel further in the gel. Gel electrophoresis can be used to determine the size, quantity, and purity of DNA fragments or proteins, as well as for DNA fingerprinting and genetic testing.

What are the application of paper electrophoresis?
Paper electrophoresis is used to analyze scientific experiments. One use in scientific experiments for paper electrophoresis is to determine the presence of HIV from blood samples.

What causes the absence of bands in gel electrophoresis?
The absence of bands in gel electrophoresis can be caused by factors such as improper loading of samples, insufficient DNA concentration, or issues with the gel or electrophoresis equipment.
What do the bands in gel electrophoresis represent?
The bands in gel electrophoresis represent different sizes of DNA fragments.
What gel is typically used in electrophoresis experiments?
The gel typically used in electrophoresis experiments is agarose gel.
