Unlocking the secrets of DNA: An introduction to electrophoresis.

Aditya Farrell*

DNA, the building block of life, holds the genetic code that makes each organism unique. Unlocking the secrets of DNA has revolutionized the field of molecular biology and has led to numerous breakthroughs in various fields including medicine and agriculture. One important tool in the study of DNA is electrophoresis. Electrophoresis is a laboratory technique used to separate and analyze DNA fragments based on their size and charge. The DNA fragments are placed in a gel and subjected to an electric field. Because DNA is negatively charged, it migrates towards the positive electrode. Larger fragments of DNA move slower than smaller fragments, resulting in a separation of the fragments based on size.
