Agarose

Agarose is a natural substance derived from seaweed, commonly used in laboratories to separate and analyze DNA or RNA molecules. When dissolved in a liquid and cooled, it forms a gel-like material that acts as a sieve, allowing smaller molecules to move through more easily while blocking larger ones. This process, called gel electrophoresis, helps scientists visualize and compare genetic material. Agarose gels are safe, easy to prepare, and widely used because they provide clear separation of DNA fragments for research and diagnostics.
