1. There is a permeable gel with a row of holes on one side.
2. Different DNA samples are placed in holes using pipette.
3. An electric current is sent through the gel, with the opposite side as positive (the DNA is negatively charged).
4. Since the larger parts of DNA cannot get far through the gel and the smaller parts can. Several bands will be formed on the gel.
5. The bands are visible under UV light
6. These bands can be used to compare genetic similarity to determine the parent/sibling.

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.
Which fragment moves the furthest in gel electrophoresis?
Smaller DNA fragments move faster and further in gel electrophoresis compared to larger fragments. The distance migrated by DNA fragments in gel electrophoresis is inversely proportional to their size.
What is a common name for gel electrophoresis?

What gel is typically used in electrophoresis experiments?
The gel typically used in electrophoresis experiments is agarose gel.

What are common troubleshooting steps for resolving issues with agarose gel electrophoresis?
Common troubleshooting steps for resolving issues with agarose gel electrophoresis include checking the quality of the agarose gel, ensuring proper buffer preparation and pH, verifying correct voltage and running time, confirming proper loading of samples, and troubleshooting equipment issues such as power supply or gel box problems.

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.
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 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
What do the bands in gel electrophoresis represent?
The bands in gel electrophoresis represent different sizes of DNA fragments.
In gel electrophoresis, which way does DNA move through the gel matrix?
In gel electrophoresis, DNA moves through the gel matrix from the negative electrode to the positive electrode.
Difference between vertical and horizontal gel electrophoresis?
Horizantal gel electrophoresis is generally used for RNA/DNA based studies, while vertical gel electrophoresis is used for protein based studies.
