Capillary sequencing
DNA sequencing involves determining the sequence of nucleotides in a given DNA fragment. The DNA sequence contains the information that living things need to survive and reproduce. Determining this sequence is therefore useful both for research aimed at knowing how organisms live and for applied subjects. In medicine, it can be used to identify, diagnose and potentially find treatments for genetic diseases and virology. In biology, the study of DNA sequences has become an important tool for the classification of species.
