H. Freeman and Company The image above shows how Anfinsen unfolded ribonuclease for his classic experiment to see if proteins contain all necessary information for adopting their folded states on their own. To achieve proper refolding and ribonuclease activity, Anfinsen must have: trick question: ribonuclease cannot adopt its folded state without the help of cellular machinery removed the mercaptoethanol followed by the urea very carefully removed both the urea and mercaptoethanol at the same time removed the urea followed by the mercaptoethanolQuestion 9 Choose the CORRECT statement. O A polypeptide chain may have abrupt changes in direction and restriction in geometry because of the presence of glycine O A polypeptide chain may have abrupt changes in direction and restriction in geometry because of the presence of valine O A polypeptide chain may have abrupt changes in direction and restriction in geometry because of the presence of arginine O A polypeptide chain may have abrupt changes in direction and restriction in geometry because of the presence of prolineQuestion 29 Which of the following statements is true regarding the formylmethionine that serves as the first amino acid in bacterial protein synthesis? A an aminoacyl-tRNA synthetase that is specific for formylmethionine attaches formylmethionine to the tRNA B the formyl group is removed during protein synthesis leaving methionine as the first residue in all bacterial proteins the formyl group donor is N¹0-formyl-tetrahydrofolate (D) the tRNA that carries formylmethionine is the same tRNA for methionine
- QUESTION 14 Identify the pictured nucleotide NH₂ N O 11 HO-P-O OH HO OH O Uracil monophosphate O Deoxythymidine monophosphate O Cytidine monophosphate O Deoxycytidine monophosphateQuestion 11. // Hint: Isoelectric focusing separates proteins based on their pI values, and can separate proteins that only differ by a net charge of ±1.±1. Recall that an amino acid residue with a negatively charged R group has a relatively low isoelectric point (pI) where it has zero net charge. Likewise, an amino acid residue with a positively charged R group has a relatively high isoelectric point (pI) where it has zero net charge. Order from Low pH to High pHQuestion 1.)Draw the main chain structure of a parallel beta sheet that has 4 amino acids in one strand and 5 in the other. Show all of the backbone atoms.Write R1, R2, R3, etc, instead of drawing side chains with the following exception: draw one proline in its entiretywith its side chain. You can put it anywhere in your sheet – I will find it. Add in all hydrogen bonds that stabilize this sheet using dashed lines.
