The Sanger method, developed at the University of Cambridge by Fred Sanger, was the first technique that enabled us to read DNA sequences on a large scale. It is extremely reliable, and it was the only tool available for several years. We also use it to sequence smaller strands of DNA with precision (up to a few thousand nucleotides). However, analyzing the DNA sequence in this way for an entire genome with millions of nucleotides could take months to years, so newer technologies are used.
At the moment, the Illumina MiSeq and HiSeq machines are the most frequently used large-scale DNA sequencing machines. In the last ten years, this technology has been used to perform the majority of our research.
In a nutshell, this technique entails cutting very long DNA strands into very small fragments, reading the sequence of each of these strands separately, and then putting them back together like a jigsaw puzzle. Small pieces are stuck to a glass plate, which is referred to as a ‘flow cell.’ Consider a sparse ‘seaweed forest’ of single DNA strands adhered to a glass rim. Thousands of different DNA strands are stuck on and then copied, resulting in a dense forest of different ‘clusters’ of similar DNA strands. Fluorescent chemicals are applied to the DNA, which stick to it and flash when exposed to light. Thousands of ‘flash photography’ photos are taken by the Illumina computer, and the details in the photographs can be used to piece together information about the original DNA sequences.

Frederick Sanger, who died recently at the age of 95, won two Nobel prizes in chemistry for his work on protein and DNA sequencing. Many people were more interested in proteins because many disease-causing mutations can be seen as variations in proteins. However, we can deduce the protein sequence from the DNA sequence, and this method has proven to be quicker, ultimately contributing to the Human Genome Project.
Sanger was a chemist who wanted to understand biological polymers, so the Human Genome Project’s popularity is focused on both biology and chemistry. Computer science is the third and most recent strand.
The ACE, Alan Turing’s Automatic Computing Engine, ran its first program in 1950, just three years before the publication of the landmark structure of DNA. EF Codd published a data model in 1970 that has proven to be important in the organization and management of vast volumes of data, despite the fact that it was not apparent to biologists at the time. Sanger’s DNA sequencing method was published in 1977, and by that time, computer scientists were able to announce the completion of the first draft of the human genome.

Bioinformatics — understanding of living systems through

In this paper, we will look at some ethical issues surrounding the increasing role of computers and computation in new genetics. Our point is that without computer science, there is no modern genetics. On two ways, computer science is critical for the modern genetics: (1) from a theoretical standpoint, and (2) from the viewpoint of geneticists in practice. In terms of (1), the modern genetics is fully saturated with principles that are fundamental to computer science. In terms of (2), recent advances in the Human Genome Project (HGP) have shown how computers influence molecular genetics practices; a significant example is the Shotgun Method’s contribution to speeding up the mapping of the human genome. The Open Source Philosophy (I computer science), which is another way computer technologies are now influencing the shaping of public policy debates surrounding genomics, poses a new challenge to the HGP.
