High-throughput is the next-generation method of DNA sequencing, which has led to the rapid acceleration of DNA sequencing and broadened knowledge in the field. It involves a rapidly expanding firing pattern to read the DNA in short fragments of 100 to 1000 base pairs, which are then overlapped with a computed analysis system. Shotgun (Sanger) sequencing is the more traditional approach, which is designed for sequencing entire chromosomes or long DNA strands with more than 1000 base pairs. Types of DNA sequencingīroadly speaking, there are two types of DNA sequencing: shotgun and high-throughput. This would work by threading single strands of DNA through nanopores in the cell membrane, which would then be read by the technology in single file. New methods are still under development, including some that utilize nanopores to sequence the DNA. The technology is expected to continue to improve in the future. The process has also reduced significantly in cost, and an entire genome would only cost a few thousand dollars at this time. Some laboratories are now able to sequence an excess of 100,000 billion nucleotide bases each year. Present and future sequencing technologyĪt this time, there are various methods and technologies that can help in the process to sequence the DNA.

This has enabled the entire human genome to be sequenced, in addition to many other species of plants and animals. The improvement in technology has corresponded to a significant increase in the rate of sequencing and accelerated growth in related research. Fluorescence-based sequencing methods were introduced to increase both the ease and speed of research. In recent decades there have been significant advancements in the technology available for DNA sequencing.
