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). Gilbert introduced a sequencing method based on chemical modification of DNA followed by cleavage at specific bases whereas … See more DNA sequencers have been developed, manufactured, and sold by the following companies, among others. Roche The 454 DNA … See more WebThe data comes out of the machine as short pieces of DNA sequence called reads. A computer takes these reads and maps them, creating a picture of the individual’s genome. Once the genome picture is assembled, another program looks for differences in the DNA, or variants, that may be causing the medical condition.
