DNA Sequencing Innovations

DNA means determining the order of the four chemical building blocks - called "bases" - that structure the DNA molecule. The sequence tells scientists the type of genetic information that's carried during a particular DNA segment. for instance , scientists can use sequence information to work out which stretches of DNA contain genes and which stretches carry regulatory instructions, turning genes on or off. additionally , and importantly, sequence data can highlight changes during a gene which will cause disease.In the DNA helix , the four chemical bases always bond with an equivalent partner to make "base pairs." Adenine (A) always pairs with thymine (T); cytosine (C) always pairs with guanine (G). This pairing is that the basis for the mechanism by which DNA molecules are copied when cells divide, and therefore the pairing also underlies the methods by which most DNA sequencing experiments are done. The human genome contains about 3 billion base pairs that spell out the instructions for creating and maintaining a person's being. DNA sequencing, technique wont to determine the nucleotide sequence of DNA (deoxyribonucleic acid). The nucleotide sequence is that the most fundamental level of data of a gene or genome. it's the blueprint that contains the instructions for building an organism, and no understanding of genetic function or evolution might be complete without obtaining this information.
