The following statements pertain to the development of the theory of the structure of DNA. Match the statement with the appropriate 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.

Verified step by step guidance

1. Step 1: Identify the statement.
2. Step 2: Determine if the statement is an observation, hypothesis, or experiment.
3. Step 3: Recognize that the statement describes a structural feature of DNA.
4. Step 4: Understand that this description is based on empirical evidence.
5. Step 5: Conclude that the statement is an observation.

Key Concepts

Scientific Method

The scientific method is a systematic approach used in scientific inquiry to explore observations, formulate hypotheses, conduct experiments, and draw conclusions. It typically involves steps such as making observations, proposing a hypothesis, designing experiments to test the hypothesis, and analyzing the results to confirm or refute the hypothesis.

Observation

Observation is the initial step in the scientific method where scientists gather information about phenomena through their senses or instruments. In the context of DNA structure, observations may include the physical characteristics of DNA, such as its shape and composition, which lead to further inquiry and hypothesis formulation.

Hypothesis

A hypothesis is a testable statement or prediction that explains a phenomenon based on observations. In the case of DNA, a hypothesis might propose that the structure of DNA is helical, which can then be tested through experiments. This step is crucial as it guides the experimental design and helps in understanding the underlying mechanisms of the observed phenomena.
