Lasers for DNA sequencing

DNA Sequencing: Refers to the method of analyzing the base sequence of specific DNA fragments to obtain biological genetic information. The emergence of DNA sequencing has greatly promoted the research and discovery of biology and medicine. DNA sequencing uses the chain termination method to introduce fluorescently labeled oligonucleotides at the end of DNA transcription. At this time, the DNA is divided into single strands of different lengths, and then passed through a laser focused beam, different fluoresceins will emit different colors of fluorescence, to achieve the purpose of labeling nucleotide sequencing.
