What is an example of a gel?
example of gel is agarose gel,
Can agarose gel be used to run proteins?
The pore size of an agarose gel is too small to allow the efficient movement of proteins. Therefore, a poly acrylamide gel is used to separate proteins according to size
Use of agrose in DNA isolation?
Agarose is not used in DNA isolation. Agarose is used to prepare a gel in which DNA fragments can be separated based on size
Why you have the range of concentration of agarose in gel electrophoresis?
increasing the agarose concentration will enable the separation of smaller fragments of DNA. the structure of the gel (agarose) consists of crosslinks, therefore the higher the concentration of agarose the more crosslinks there will be and smaller size "holes" for the DNA to travel through (also the other way around, with less concentrated agarose)
What is a difference between 2 percent and 3 percent agarose gel?
the thickness of the gel varies as you change the conc. of agarose from 2 to 3 percent. the conc. of loading of samples that gel can handle varies.
What is agarose and what is the TM value of agarose?
Agarose is a linear polysaccharide used for gel mediums. Tm (melting temp) is about 85 C.
Why agarose gel electrophoresis is not used for protein analysis?

Use of agrose in DNA isolation?
Agarose is not used in DNA isolation. Agarose is used to prepare a gel in which DNA fragments can be separated based on size
What is role of agarose of electrophoresis?
agarose helps in the separation of DNA bands by controlling the pore size of agarose gel
Is agarose gel electrophoresis suitable for only gram negative plasmid DNA?
Agarose gel electrophoresis is suitable for ALL DNA.
Why you have the range of concentration of agarose in gel electrophoresis?
increasing the agarose concentration will enable the separation of smaller fragments of DNA. the structure of the gel (agarose) consists of crosslinks, therefore the higher the concentration of agarose the more crosslinks there will be and smaller size "holes" for the DNA to travel through (also the other way around, with less concentrated agarose)
Function of agarose in agarose gel electrophoresis?
Agarose is used in gel electrophoresis to separate nucleic acids (like DNA) by size, charge an other physical properties. Gel electrophoresis uses an electrical current to make particles move. For example, DNA is negative, so it'll travel towards to positive electrode of the gel box. Agarose has small pores through which a DNA can travel. Bigger fragments of DNA travel shorter distances, because it takes longer for them to navigate through the pores of the agarose gel. Identically sized pieces of DNA will travel the same distance, which is why you get bands (DNA with loading dye) after you run a a gel.
What holds agarose gel together?
Stuff
What does the accuracy of the fragment sizes tell you about the resolving ability of agarose-gel electrophoresis?
The larger fragements will not be very accurate because they cannot resolve in high consentrations of the agarose in the gel. The percent of agarose in the gel affects the ability to resolve larger fragements of DNA
