In 1950 Erwin Chargaff published a scientific paper showing the percentages of the nitrogen bases adenine (A), thymine (T), cytosine (C), and guanine (G) in the DNA of different types of organisms. His analysis of the data revealed key understandings about the structure of DNA.

An analysis of an octopus’s DNA determines that the nitrogen base thymine makes up 18 percent of the genome. Which of the following best represents the percent of guanine Chargaff would have found in the octopus’s genome?


A.18%


B. 32%

C.36%


D.64%
