DNA base sequencing

Part of the DNA of a mouse and fly with highlighted comparisons which are the same

The DNA of organisms can be compared by looking at the order of the bases (As, Ts, Gs and Cs) in each.A DNA signature comparison graph that shows how related species to humans are similar

Closely related species will have a higher percentage of similarity in their DNA base order. For instance, humans and chimps share around 98%, while humans and mice share about 85%.
