Wiki Article

DNA sequencing, a revolutionary technology revolutionized our understanding of life itself. By uncovering the precise sequence of nucleotides in a strand of DNA, we gain knowledge into an organism's traits. This powerful tool has applications across diverse fields, from medicine to forensics.

Sanger Sequencing: A Classic Approach to Genomic Analysis

Sanger sequencing, also known as chain-termination sequencing, revolutionized the realm of genomics upon its discovery by Frederick Sanger in the late 1970s. This technique utilizes modified nucleotides to terminates DNA synthesis, generating short fragments that can be sequenced. By comparing the sizes of these fragments, researchers can decode the precise order of nucleotides in a DNA molecule.

Sanger sequencing's precision and relatively simplicity have made it a pivotal method for a wide range of applications, including mutation detection. While advanced sequencing technologies have emerged, Sanger sequencing remains a essential component in genomics research due to its trustworthiness.
