define resolution in X-ray crystallography in your own words. How does resolution compare with the atomic distances that characterize chemical bonds in for example protein? If you have a structure obtained at 3.5Å resolution could you draw detailed conclutions concerning mechanism of action?
explain the answer, why does it become a ring? when does this
happen and why?
NaOH hint: product has a satom.in a ring
X-ray diffraction operates at wavelengths of ~1 A in order deliver Angstrom-resolution protein structures. [4] Explain, why and how NMR spectroscopy, which operates at much longer, radiofrequency wavelengths (10 ^m), can deliver protein structures of comparable (Angstrom) resolution. As an NMR spectroscopes, do you prefer larger or smaller values for the duration of the 90degrees ovules for the target nucleus/channel (e.g. for 1H)? Justify.
Explain why MRI is safe compared to X-ray scanner using the energy of the electromagnetic radiation.
TCP flow (WHAT is it, WHEN does it become relevant, WHY is it needed, WHERE would it be used, WHO would need it AND HOW to use it - AN EXAMPLE)
1. When during its life cycle is Sordaria diploid? When specifically does it become diploid? When does it become haploid again? 2. If it mainly exists as a haploid organism, what advantage(s) does Sordaria gain from reproducing sexually? 3. Why is Sordaria a good model organism for studying crossing over during meiosis?
Can someone please explain to me, why the current affects the x ray image contrast and the density of the x ray image? Also then again why would does the voltage affect these contrast and density. Would they affect the x ray image in any other ways And also what specific factors would you use these for in medical imaging using x rays - e.g. mammography, imaging of the lungs, please don't just state what, but explain why as well?
BIOCHEM QUESTION: When solving a protein structure using X-ray crystallography, the crystallographer generates a 3-D grid called an electron density map based on the observed diffraction pattern. The higher the resolution, the more detailed the electron density map and therefore the easier it is to identify what atoms (and therefore what amino acids) are in a given position. Based on the three choices below, in which of the following groups could the two of amino acids be the easiest to...
