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 ).
Automated DNA-sequencing instruments (DNA sequencers) can sequence up to 384 DNA samples in a single batch. Batch runs may occur up to 24 times a day. Batch runs may occur up to 24 times a day. DNA sequencers separate strands by size (or length) using capillary electrophoresis , they detect and record dye fluorescence, and output data as ...
In 1982, Smith did post-doctorate work with Leroy Hood at the California Institute of Technology, where he created the world's first fluorescence-based automated DNA sequencing instrument. [ 2 ] [ 4 ] [ 5 ] During the early 80s he also worked as a consultant for Applied Biosystems , who were able to commercialise the sequencing process he ...
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and ...
The protein sequencer, DNA synthesizer, peptide synthesizer, and DNA sequencer were commercialized through Applied Biosystems, Inc. [13]: 218 and the ink-jet technology was commercialized through Agilent Technologies. [9] [10] The automated DNA sequencer was an enabling technology for the Human Genome Project. [7]
Phred quality scores shown on a DNA sequence trace A Phred quality score is a measure of the quality of the identification of the nucleobases generated by automated DNA sequencing . [ 1 ] [ 2 ] It was originally developed for the computer program Phred to help in the automation of DNA sequencing in the Human Genome Project .
Polony sequencing is generally performed on paired-end tags library that each molecule of DNA template is of 135 bp in length with two 17–18 bp paired genomic tags separated and flanked by common sequences. The current read length of this technique is 26 bases per amplicon and 13 bases per tag, leaving a gap of 4–5 bases in each tag.
The two sequencer and synthesizer products allowed molecular biologists to clone genes by building oligonucleotides with the desired protein's DNA sequence. [1] Automated DNA sequencing began at the California Institute of Technology, using fluorescent dyes, with Rights to the technology granted to Applied Biosystems. [1]
