DNA sequencing is unique in humans. Aside from rare cases of identical twins, no two people will share the same exact DNA. However, of the roughly three billion base pairs that complete the human genome, more than 99% are the same in all people. The closest living relative to humans, the chimpanzee, shares 96% of our DNA. Despite a seemingly high comparison rate, humans and chimpanzees still have 40 million different DNA ______.

These base pairs link to a phosphate molecule and a sugar molecule, creating a larger structure known as a nucleotide. Nucleotides are arranged into spiral formations called double helixes. The double helix is built similarly to a ladder, the rungs are made of base pairs (either A&T combinations or C&G combinations) and the sidepieces are made of sugar and phosphate molecules. DNA IN CLASSIFYING LIVING THINGS Taxonomy The field of study that determines how living things are classified. It entails the description, naming, and classification of living things, which helps us categorize organisms so we can more easily communicate biological information. Taxonomy uses hierarchical classification to help scientists understand and organize the diversity of life on our planet. Hierarchical classification basically means that we classify groups within larger ______.
