- is there a role for the protein data bank in biochemical research? if so, describe it. I am so confused on what he is asking our textbook doesn't talk about that. we are using the principle of biochemistry eighth edition: David L.NelsonMany studies that have revealed important biochemical processes in human beings, including those that underpin the development of new drugs, have been conducted in other organisms. These organisms include mammals such as mice and rats but also extend to single-celled organisms such as yeast. Why is this approach often productive?Why does a sufficiently bright flash of light delivered over a short period of time produce a sensation of temporary blindness? Explain the molecular and biophysical properties in detail.
- Explore the the biochemical makeup of a human body in the context of the classes of life's organic moleculesBiomolecules' three-dimensional structure is more evolutionary conserved than their sequence. Why?Chemically, RNA is less stable than DNA. Why? RNA can be ionized more easily than DNA because is it a single strand. The presence of an OH group at C2' in RNA makes it more susceptible to hydrolysis RNA is single stranded, while DNA is double stranded, making DNA a more stable molecule. RNA is a much shorter molecule than DNA The presence of an OH group at C2' in DNA makes it less susceptible to hydrolysis
- What kind of techniques would be needed to take the structure properly taken into account in biochemical experiments?DNA Protein Synthesis Test STRUCTURE OF DNA If 37% of a cell's nucleotides are cytosine, which of the following would also be true? *You may use the calculator function on the sidebar to help with the math. O 13% are adenine O 26% are thymine O 74% are guanine O 74% are adenine 2Water is attracted to anything charged (ionized) or polar (slightly charged) Recall that opposite charges attract. Because of its partial positive and negative charges, water is attracted to molecules that are charged or polar, including other water molecules. The attraction between water molecules is a weak bond called a hydrogen bond. These bonds are not just between water molecules though. These bonds can be between other kinds of molecules too. For example, they hold two strands of DNA together! Draw several water molecules aligned with one another according to their charges and show little dotted lines to indicate the weak fleeting H-bonds between the molecules: The polarity of water allows it to dissolve (pull apart) ions such as salts. Draw a Na+ ion being dissolved (surrounded) by some water molecules (aligning the water molecules properly): Any type of ion or polar molecule that water is attracted to is described as HYDROPHILIC.
- Both DNA and RNA are sensitive to alkaline hydrolysis. However, RNA is more sensitive to alkaline hydrolysis because of: The presence of 2' hydroxyl group The presence of 1' uracil nitrogenous base The presence of 5' phosphate group The presence of 3' hydroxyl groupChemistry I'm thinking DEAE makes the most sense but I want a second opinion. I'm also not sure how to elute the protein. I'll rate with a good answer, thanks![Ten - Biomolecules] INSTRUCTIONS — Answer the following multiple-choice questions and EXPLAIN in 3-5 sentences why you chose that answer. — Answer properly Questions; Thomas was purifying an enzyme from a homogenate of muscle cells. He went through seven steps of purification and found that the enzyme activity was the same as the homogenate value. On the eighth step, when the protein washighly pure, the enzyme activity rose to five times that of the homogenate value. Can you suggest a possible reason? A. the homogenate assay was wrong B. step eight has co-purified an activator of the enzyme. C. the enzyme has an inhibitor present in the muscle cell homogenate D. the temperature at step eight was just right for the enzyme activity.
