Every pathogen either virus or bacteria has its own specific DNA and DNA sequencing recognizes similarities while study sequence of nucleotide.
Further explanation
DNA sequencing
It is a phenomenon in which a piece of DNA is taken and its nucleotide bases (guanine, adenine, thymine and cytosine) are determined. It is useful to study genetic information of an organism. Earlier technique of RNA sequencing was used.
Invention of DNA sequencing
Frederick Sanger was the first person who used this technique and was invented in 1970s. This technique is used in various field of biology such as molecular biology, Medicine, evolutionary biology, biotechnology and forensics.
Advantages of DNA sequencing
It provides accurate information Â
Genome remains same throughout life so it is done once in life
It is not an expensive method so we can say that it saves money
Genomic information can be obtained which is required for various purposes as health care
Identify defective genes
Disadvantages of DNA sequencing
It is a very time taking technique
It cannot detect translocation, deletion and insertion
