The following statements pertain to the development of the theory of the structure of DNA. Match the statement with the appropri
ate step (observation, hypothesis, experiment designed to test hypothesis) in the scientific method.a. Two strands of DNA wind around one another in a helical structure.b. In a sample of DNA, there are equal amounts of the bases A and T and equal amounts of the bases C and G.c. Direct X-rays at a sample of crystallized DNA and interpret the diffraction pattern for structural information.
A scientific method involves various steps to explain a natural phenomenon of nature. It begins with making an observation which leads to asking the scientific question. The researcher does background research and proposes a hypothesis which could be tested through experiments. The experiments could prove or disprove the hypothesis based on the results.
In the given question the observation made is an equal amount of A and T and G and C are observed. It leads to a hypothesis which shows that this could have happened due to the winding of two strands of DNA and the experiments was performed through X-ray diffraction pattern.
Thus, the selected options are the correct answer.
