DNA Sequencing:

DNA sequencing is the procedure of reading the nucleotide bases in a DNA molecule. It involves any technology or method which is used to determine the order of the four bases- guanine, adenine, cytosine and thymine in a strand of DNA.

Knowledge of DNA sequences has turn into indispensable for basic biological research and in numerous applied fields like as biotechnology, forensic biology, diagnostic and biological systematics. The advent of DNA sequencing has considerably accelerated biological discovery and research. The rapid speed of sequencing attained with modern DNA sequencing technology has been instrumental in the sequencing of complete DNA sequences or genomes of numerous kinds and species of life, involving the human genome and other complete DNA sequences of several plants, animal and microbial species. An instance of the results of automated chain-termination DNA sequencing.

The first DNA sequences were formed in the early year of 1970s through academic researchers using laborious technology based on 2-D chromatography. Subsequent the development of fluorescence-based sequencing methods with automated analysis, DNA sequencing has become simple and orders of magnitude faster.
