Exploring the critical functions of macromolecules such as DNA, RNA, proteins, and polysaccharides in living organisms. These components are vital for genetic information storage, structural integrity, and biochemical processes. Gel electrophoresis, a technique used to separate these macromolecules by size and charge, is essential in molecular biology research, diagnostics, and education. It aids in DNA fingerprinting, gene expression analysis, and the study of genetic disorders.

Nucleic acid electrophoresis uses agarose gels to separate DNA and RNA fragments
Protein electrophoresis uses polyacrylamide gels, such as SDS-PAGE, to separate denatured proteins
The concentration of the gel used in electrophoresis is determined by the size and charge of the macromolecules being analyzed
The gel is prepared with wells for sample loading and placed in an electrophoresis chamber filled with a conductive buffer
Samples are mixed with a loading dye and carefully pipetted into the wells
When an electric current is applied, the macromolecules migrate through the gel and are stained with a dye specific to their type for visualization
A molecular weight marker is run alongside the samples to estimate the molecular weights of the separated fragments
Gel electrophoresis is used to verify the size and purity of PCR products
Gel electrophoresis is used to prepare DNA fragments for cloning or sequencing
Gel electrophoresis is used to analyze gene expression by separating mRNA transcripts
Gel electrophoresis is used in forensic science for DNA fingerprinting and identification purposes
Gel electrophoresis is used in the study of genetic disorders and the development of gene therapies
