Question

X-ray crystallography resolution depends primarily on:

• A. Sample color
• B. Crystal quality and size
• C. Sample temperature
• D. Detector brand

Hint:

Good X-ray crystallography resolution mainly depends on good crystal quality and proper crystal size.

Answer 1

The Correct Option is B

Concept:
In X-ray crystallography, resolution tells how clearly atomic details can be observed in the electron density map.

Step 1: Role of crystal quality.
A well-ordered crystal gives sharp and strong diffraction spots. Poor-quality crystals give weak or smeared diffraction patterns.

Step 2: Role of crystal size.
A suitable crystal size improves diffraction intensity and helps in better data collection.

Step 3: Eliminate wrong options.
Sample color does not determine resolution. Detector brand may affect data collection quality but is not the primary biological factor. Temperature can influence stability but crystal quality is the main factor. \[ \therefore \text{Correct Answer is (B)} \]
