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)
Agarose gel electrophoresis.
Agarose solution is a gel-like substance used in molecular biology and biochemistry for techniques like agarose gel electrophoresis. It is derived from seaweed and forms a matrix in which DNA, RNA, and proteins can be separated based on size. The concentration of agarose in the solution determines the size range of molecules that can be effectively separated.
Agarose concentration refers to the amount of agarose powder mixed with buffer solution to make a gel for DNA electrophoresis. Typical concentrations range from 0.5% to 2%, with higher concentrations providing better resolution for larger DNA fragments. The chosen concentration depends on the size of the DNA fragments being analyzed.

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.

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.
The purpose of using a buffer in agarose gel electrophoresis is to maintain a stable pH and provide ions that help conduct electricity, allowing the DNA or other molecules to move through the gel.
The gel in gel electrophoresis is typically made of agarose or polyacrylamide. It acts as a matrix to separate DNA, RNA, or proteins based on size and charge as an electric current passes through it. Agarose gels are commonly used for DNA analysis, while polyacrylamide gels are often used for higher resolution protein separation.
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.
