An electrophoresis apparatus is a laboratory device used to separate charged molecules, such as proteins or nucleic acids, based on their size and charge through an electric field. The apparatus typically consists of a gel matrix (like agarose or polyacrylamide), electrodes, and a power supply. When an electric current is applied, the molecules migrate through the gel, allowing for analysis and visualization of the separated components. This technique is widely used in molecular Biology for applications such as DNA sequencing, protein analysis, and genetic fingerprinting.

Where is the DNA placed in gel electrophoresis apparatus?
The DNA is loaded into wells at one end of the gel in gel electrophoresis apparatus. When an electric current is applied, the DNA is separated based on size as it moves through the gel towards the opposite end.
What do the bubbles in the electrophoresis box prove?
The bubbles in the electrophoresis box indicate that an electric current is flowing through the gel, which is essential for the separation of DNA, RNA, or proteins. These bubbles are typically produced by the electrolysis of water when an electric current is applied, confirming that the electrophoresis apparatus is functioning properly. The presence of bubbles does not directly relate to the results of the separation but shows that the system is operational.
What is a common name for gel electrophoresis?
Agarose gel electrophoresis.
What property of DNA causes it to migrate to the opposite pole of a electrophoresis apparatus?
DNA is negatively charged due to its phosphate backbone. When an electric field is applied during electrophoresis, the negatively charged DNA molecules migrate towards the positive electrode (anode). This movement allows for the separation of DNA fragments based on size, with smaller fragments traveling faster and farther than larger ones.
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.

Pictures of science apparatus used in school labs I need pictures of science apparatus used in school labs?
To get all of kinds science equipment/apparatus go to Wikipedia.com and look up pH meter, high performance liquid chromatography (HPLC), gas chromatography mass spectroscopy (GC/MS), pipettes, vortex, electrophoresis, and a desiccator. This should get you started.

Can a gel electrophoresis be performed both horizonnally and vertically?
yes for example 2D gel electrophoresis
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.
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.
