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. (c) Direct X rays at a sample of crystallized DNA, and inter-pret the diffraction pattern for structural information.

Verified step by step guidance

1. Identify the nature of the task: The task involves understanding the role of a specific action within the scientific method.
2. Recognize the key components of the scientific method: These typically include making observations, forming hypotheses, and conducting experiments to test these hypotheses.
3. Analyze the statement given: The statement describes the action of directing X-rays at a sample of crystallized DNA and interpreting the diffraction pattern to gather structural information.
4. Determine the type of scientific method step: Consider whether the action involves observing natural phenomena, proposing a speculative explanation, or actively performing a procedure to validate a hypothesis.
5. Classify the statement: Since the action involves performing a specific procedure to obtain data that can be used to support or refute a hypothesis, classify it as an 'experiment designed to test hypothesis'.

Key Concepts

Scientific Method

The scientific method is a systematic approach to inquiry that involves making observations, forming hypotheses, conducting experiments, and drawing conclusions. It is fundamental in scientific research as it provides a structured framework for investigating phenomena and validating theories.

X-ray Crystallography

X-ray crystallography is a technique used to determine the atomic and molecular structure of a crystal by directing X-ray beams at it. The resulting diffraction pattern provides critical information about the arrangement of atoms within the crystal, which is essential for understanding the structure of complex molecules like DNA.

Diffraction Pattern Interpretation

Interpreting a diffraction pattern involves analyzing the angles and intensities of scattered X-rays to deduce the arrangement of atoms in a crystal. This process is crucial in structural biology, as it allows scientists to visualize the three-dimensional structure of biomolecules, leading to insights into their function and interactions.
