بخشی از مقاله
What makes organisms different?All living organisms have the same DNA structure with the deoxyribose (sugar) and phosphate backbone and the same four bases. The only thing that distinguishes the DNA of organisms is the order and number of the nitrogen bases. Human DNA differs from chimpanzees by 1.6%.
Our DNA is structurally the same as a cow, chicken, lily, corn etc.
