Agarose, a polysaccharide extracted from seaweed, is widely utilized in molecular biology for its unique gel-forming properties. When dissolved in water and heated, agarose forms a gel matrix upon cooling, creating a porous network ideal for separating biomolecules based on size. This technique, known as agarose gel electrophoresis, is fundamental in molecular biology for analyzing DNA, RNA, and proteins. Agarose gels provide a platform for visualizing and characterizing nucleic acids and proteins, enabling researchers to determine fragment sizes, purify specific DNA fragments, and assess sample integrity. With its simplicity, versatility, and reproducibility, agarose gel electrophoresis remains an indispensable tool in molecular biology laboratories worldwide. https://www.dnatestingexperts.com/agarose-an-essential-tool-in-molecular-biology/
