Laser for gene sequencing

Gene sequencing: also known as DNA sequencing, it 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. Gene sequencing uses chain termination method, which introduces fluorescent labeled oligonucleotides at the transcription end of DNA. At this time, DNA is divided into single strands of different lengths, which are then focused by a laser beam. Different fluorescent elements emit different colors of fluorescence, achieving the purpose of labeling nucleotide sequencing.
