example of gel is agarose gel,
The main difference between a 2% and a 3% agarose gel is the concentration of agarose in the gel. A 3% agarose gel will have a higher agarose concentration, resulting in a higher resolving power for separating larger DNA fragments compared to a 2% agarose gel. However, a higher percentage agarose gel may also have a tighter mesh size, making it harder for larger DNA fragments to migrate through the gel.

Agarose gel electrophoresis.
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.
Agarose gel electrophoresis is suitable for ALL DNA.
Agarose is a linear polysaccharide used for gel mediums. Tm (melting temp) is about 85 C.
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 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 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.
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.
