Szekvenáláson refers to the process of determining the order of nucleotides within a DNA or RNA molecule. This ordered sequence of genetic information is fundamental to understanding the structure and function of genes and genomes. The development of DNA sequencing technologies has revolutionized biology and medicine, enabling researchers to read the genetic code of organisms.

Early sequencing methods, such as the Sanger sequencing method developed by Frederick Sanger, involved chain termination. This technique, while groundbreaking, was labor-intensive and relatively slow for sequencing large amounts of DNA. The advent of next-generation sequencing (NGS) technologies dramatically increased throughput and reduced costs, allowing for rapid sequencing of entire genomes. NGS technologies employ various approaches, including sequencing by synthesis and single-molecule sequencing.

The applications of DNA sequencing are vast. It is crucial for identifying genetic variations associated with diseases, allowing for personalized medicine and the development of targeted therapies. In evolutionary biology, sequencing helps reconstruct evolutionary relationships between species and understand the genetic basis of adaptation. It also plays a significant role in forensics, agriculture, and the study of microbial communities. The interpretation of sequencing data, often referred to as bioinformatics, involves sophisticated computational tools and algorithms to analyze and make sense of the vast amounts of genetic information generated.
