The purpose of DNA sequencing is to determine the precise sequence of nucleotides (adenine, guanine, cytosine, and thymine) in a DNA molecule. It helps in understanding the genetic information encoded in the DNA and provides insights into gene function, heredity, evolution, and various biological processes. DNA sequencing is widely used in scientific research, medicine, biotechnology, and forensic sciences for applications such as identifying genetic diseases, studying genetic variation, tracing ancestry, studying microbial communities, and developing new drugs or therapies.
