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.
example of gel is agarose gel,
Agarose gel electrophoresis.
The label "1" on agarose gel material typically refers to the concentration of agarose in the gel, which is usually expressed as a percentage. For example, a 1% agarose gel contains 1 gram of agarose powder dissolved in 100 milliliters of buffer solution. This concentration affects the gel's porosity and is chosen based on the size of the DNA fragments being analyzed. Higher percentages create a denser gel suitable for separating smaller fragments, while lower percentages are used for larger fragments.
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.
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)
Check the answer for How do you make an electrophoresis gel?
Agarose gel electrophoresis separates biomolecules based on size and charge, while SDS-PAGE separates based on size and mass. Agarose gel is used for larger molecules like DNA and RNA, while SDS-PAGE is used for proteins. Agarose gel uses a gel made from agarose, while SDS-PAGE uses a gel made from polyacrylamide.

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
Agarose gel electrophoresis.
Agarose gel electrophoresis is suitable for ALL DNA.
Agar is a gelatinous substance derived from seaweed, commonly used in microbiology for culturing bacteria. Agarose is a type of agar that has been purified and is specifically used in gel electrophoresis for separating DNA fragments based on size.

Agarose is a linear polysaccharide used for gel mediums. Tm (melting temp) is about 85 C.
The gel typically used in electrophoresis experiments is agarose gel.
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.
Agarose is used in gel electrophoresis as a medium to separate DNA fragments based on their size. When an electric current is passed through the agarose gel, DNA molecules move through it at different speeds, allowing for separation by size. Agarose forms a matrix that acts as a sieve, slowing down larger DNA fragments more than smaller ones.
