Which of the following mutations would most likely keep the transitions of T state to R state in hemoglobin unchanged, or similar to thetransitions that occur in the native molecule? The three-letter codes for amino acids are used, and the numbers following the aminoacids designate the amino acid position in the protein. By convention, the original, native amino acid is listed fırst, followed by themutational change.Choose one:O A. Asp94→Ile94O B. Tyr42→Phe42O C. Asp94 Glu94O D. Tyr42-Gly42

Amino acids are organic compounds which contain amino group, carboxyl group and functional groups…

Answered: Which of the following mutations would…

Hemoglobin is considered to be a tetrameric complex with a 64 kDa (α β)2. When attempting to purify hemoglobin, we must first purify the α and β monomers (about 16 kDa each) to prepare the tetramer. This is formed from the dimer intermediate: 2 α + 2 β -> 2 αβ -> (α β)2. The graph given represents a size-exclusion chromatogram after the refolding of the hemoglobin tetramer Using the size-exclusion chromatogram given, 1. Draw an SDS-Page Gel with a reducing agent such as BME using the three peaks listed on the graph.
There are around 20 different versions of this molecule, which create different proteins when linked up in different sequences (like different letters making different words).

After staining an SDS-PAGE gel with Coomassie Blue G-250, the protein bands are visualized by de-staining the gel in a Coomassie Blue G-250 de-staining solution. This solution is made up of 10% acetic acid, 50% methanol, and 40% distilled water. How much of each of these components do you need to prepare 5 liters of Coomassie Blue G-250 de-staining solution?
The folding of intrinsically disordered proteins is prevented by the presence of Ser, Lys, and Glu residues. What do these amino acids have in common? Why do they disrupt IDPs?
The following amino acids that are often found inside globulin molecules are () A, Tyr B, Phe C, Asn D, Glu True of false 1. In the de novo synthesis of purine nucleotides and pyrimidine nucleotides, base rings are first synthesized and then corresponding nucleotides are formed with phosphoribose. () 2. Transcription is the process of transferring genetic information from DNA to RNA. DNA is synthesized under the catalysis of RNA polymerase, and the direction of synthesis is from the 5 'end to the 3' end. () 3. The change of protein conformation is caused by the breaking of covalent bonds within the molecule. () 4. In very high and very low pH solutions, amino acids exist mainly in non-ionic form. () 5. The active center of an enzyme usually consists of several amino acid residues adjacent to each other in the primary structure. ()
