How does a dna sequencing machine work

A DNA sequencer is a scientific instrument used to automate the DNA sequencing process. Given a sample of DNA, a DNA sequencer is used to determine the order of the four bases: G (guanine), C (cytosine), A (adenine) and T (thymine). This is then reported as a text string, called a read. Some DNA sequencers … See more The first DNA sequencing methods were developed by Gilbert (1973) and Sanger (1975).
