Explanation:
The correct order of the steps in the scientific method would be to ask questions, make hypothesis, test the hypothesis, analyze the results, draw conclusions, and communicate the results. The correct option would be D
The scientific method refers to a rational order of steps followed by scientists in order to understand natural phenomena.
The method starts by asking questions or making observations about a phenomenon, formulating hypotheses based on the observation, testing the hypothesis using experiments, analyzing the results of the experiment, drawing conclusions based on the result, and then communicating the outcome to the public.

Explanation:
Watson & Crick discovered that DNA is composed of two (2) strands of DNA running antiparallel to each other. One strand is oriented in the 5’ -> 3’ direction while the other is oriented in the 3’ -> 5’ direction. The nitrogenous bases of the strands are found in between the two-strand backbones and they form hydrogen bonding with each other. Specifically, pyrimidines (Cytosine and Thymine) pair with purine (Adenine and Guanine).
The space between the strands is even throughout like a ladder with rungs of equal lengths. However during the twisting on the DNA helix, there are major grooves and minor grooves that form along the helix because of the nature of how the nitrogenous bases are attached to their respective strand. They do not project from their strands at 90 degrees.
