Define the terms resolution and R-factor as used in X-ray crystallography. Why are these values important in selecting structures to use for modeling and other calculations? Diagram the sitting drop crystallization procedure. What factors might you vary the experimental conditions to search for good crystals?

What's the importance of X-ray crystallography in inorganic chemistry?

compare and contrast nmr and x ray crystallography for protein structure determination.

One of the main assumptions in protein X-ray crystallography is, that proteins (for that matter all other biological macromolecules as well) in their crystalline state have folding topologies identical to those of the proteins in solutions or in their natural cellular environment. Several lines of evidence support this notion. Which one of the following is the most compelling to you? (Rate A trough F from most to less compelling and give your reasoning. A) Except in some isolated cases, the...

A) Describe the process of x-ray crystallography including the steps carried out in the information provided. Compare this to both circular dichroism and 2DNMR, identifying at least one benefit and one drawback of each as compared to X-ray crystallography. B) describe how SDS PAGE is carried out including what is generally mixed with the protein samples (and why), what is used as a standard, and what determines the final position of the protein. What are some differences between SDS PAGE...

For 2D NMR, X-ray crystallography, and Cryo EM, what level of protein structure can they resolve?...

For 2D NMR, X-ray crystallography, and Cryo EM, what level of protein structure can they resolve? Primary, secondary, tertiary, or quaternary? It can be multiple. So far I have tertiary and quaternary for X-ray crystallography, quaternary for Cryo-EM, and secondary and tertiary for 2D NMR but I am not sure about these.

Explain how X-ray observations are used to determine the temperature, T (r), and den- sity, ρgas, of the hot gas in an elliptical galaxy. What quantities are observed directly and how are they used to ultimately determine T and ρgas?

Why is resolution more important than magnification? Thanks
