The agarose gel acts as a matrix that slows down the dna segments as they move to the opposite charged end of the gel. A larger segment will have a tougher time moving through the gel, while a smaller segment will move faster because it is easier to move it through the gel.

Minimum DNA on agarose to visualize?
you need at least 20ng to visualize it on an agarose gel along with EtBr or GR safe
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)
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 an example of a gel?
example of gel is agarose gel,
What is an agarose gel and what is it used for?
Agarose gel electrophoresis is the easiest and most common method used in biochemistry and molecular biology in separating DNA or RNA molecules according to their size.
What is role of agarose of electrophoresis?
agarose helps in the separation of DNA bands by controlling the pore size of agarose gel
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.
What is an agarose?
An agarose is a polymeric cross-linked polysaccharide extracted from the seaweed agar and used to make gels.
Minimum DNA on agarose to visualize?
you need at least 20ng to visualize it on an agarose gel along with EtBr or GR safe
Preparation of 1 percent agarose gel or How to prepare 1 percent agarose gel?
Check the answer for How do you make an electrophoresis 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)
What holds agarose gel together?
Stuff
Agarobiose?
is the repeating unit of the agarose polymer
High concentration agarose will?
impede migration
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 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
