What is DNA sequencing used for?

DNA sequencing is used to identify individual genes within the DNA of any organism. This information can be used to identify variants and mutations that cause diseases and disorders.

The process of DNA sequencing is used today by researchers and physicians around the world. This is due in large part to the success of a research project known as the Human Genome Project, which began its work in 1990. The HGP sought to map all three billion base pairs of the human genome, according to the National Human Genome Research Institute.

Genetic sequencing methods have helped scientists to discover more than 1,800 disease-causing genes and to create more than 2,000 genetic tests to identify medical conditions, according to the National Institute of Health.
