Question

applications of paper chromatography in DNA sequencing

Answer 1

Paper chromatography is applied in forensic laboratories to identify and analyze long molecules such as proteins, DNA, and RNA sequencing. A basic technique used foe forensics is gel electrophoresis. Since different organisms have a different DNA sequence, paper chromatography is used in separating different molecules, normally pigments. It separates molecules based on biochemical properties, using a given mixture of molecules and finding the ability of the molecules to interact with the solvent phase. The more the molecule interacts with the solvent phase, the lower the distance it travels on the paper.
