Verified step by step guidance

Understand the methods used for protein structure determination: X-ray crystallography, cryo-electron microscopy, NMR spectroscopy, and amino acid sequence analysis. Each method has specific applications and limitations.

Evaluate the statement about cryo-electron microscopy: Cryo-electron microscopy is typically used for large macromolecular complexes, not small peptides. This statement is false.

Assess the statement about amino acid sequence analysis: While amino acid sequence analysis provides valuable information about protein structure, it cannot solely determine the three-dimensional structure of a protein. This statement is false.

Examine the statement about X-ray crystallography: X-ray crystallography is a powerful technique that can provide atomic-level details of protein structures. This statement is true.

Analyze the statement about NMR spectroscopy: NMR spectroscopy is specifically used to study proteins in solution, making this statement false. NMR is valuable for understanding dynamic and flexible regions of proteins.
