Question
Chapter 6, Problem 5P
Interpretation Introduction
Interpretation:
The mass of RNA required in grams if the pool has at least a single molecule of each sequence is to be calculated.
Concept introduction:
The RNA consists of four base pairs. Four base pairs of RNA molecule are adenine, uracil, guanine and cytosine. The base adenine is complementary with uracil and guanine is complementary with cytosine.

- Peptide mass determination. You have isolated a proteinfrom the bacterium E. coli and seek to confirm its identityby trypsin digestion and mass spectrometry. Determinationof the masses of several peptide fragments has enabled youto deduce the identity of the protein. However, there is adiscrepancy with one of the peptide fragments, whichyou believe should have the sequence MLNSFK and an(M 1 H)1 value of 739.38. In your experiments, yourepeat edly obtain an (M 1 H)1 value of 767.38. What isthe cause of this discrepancy and what does it tell youabout the region of the protein from which this peptide isderived?arrow_forwardOnly galactose need.

BAD functions as an aß heterodimer, and the a subunit (25kD) and ß subunit (75KD) are held together by an electrostatic interaction between K in the a subunit and D in the B subunit. You are trying to dissociate the BAD subunits to prevent pathogenesis in the bacteria. Which mutation would you make to prevent the BAD subunits from forming a dimer? Assume neutral pH. (A) introduce AAA → AGA point mutation in the a subunit gene (B) introduce GAC → GAG point mutation in the ß subunit gene (C) introduce GAT → CGT point mutation in the ß subunit gene (D) introduce two point mutations: AAG → GTG in the a subunit gene & GAC → CTC in the B subunit gene (E) introduce two point mutations: AAA → TGC in the a subunit gene & GAT → TGT in the B subunit gene second base in codon A TGT Cys TGC Cys TTT Phe…arrow_forward
- Ionization State of Histidine.Each ionizable group of an amino acid can exist in one of two states, charged or neutral. The electric charge on the functional group is determined by the relationship between its pKa and the pH of the solution. This relationship is described by the Henderson-Hasselbalch equation. 1.Histidine has three ionizable functional groups. Write the equilibrium equations for its three ion-izationsand assign the proper pKa for each ionization. Draw the structure of histidine in each ionization state.What is the net charge on the histidine molecule in each ionization state? 2.Which structure drawn in (1) corresponds to theionization state of histidine at pH 1, 4, 8, and12?Note that the ionization state can be approximated by treating each ionizable group independently. 3.What is the net charge of histidine at pH 1, 4, 8, and 12? For each pH, will histidine migrate to-ward the anode (+) or cathode (-) when placed in an electric field?arrow_forward2. Subunit Composition of a Protein. A protein has a molecular mass of 400 kDa when measured by size-exclusion chromatography ( F). When subjected to gel electrophoresis in the presence of sodium dodecyl sulfate (SDS), the protein gives three bands with molecular masses of 180, 160, and 60 kDa. When electrophoresis is carried out in the presence of SDS and dithiothreitol (=), three bands are again formed, this time with molecular masses of 160, 90, and 60 kDa. Determine the subunit composition of the protein. Note: dithiothreitol is a reagent to beak down the disulfide bonds.arrow_forwardPeptides. 1. Draw the peptide Ala-Glu-Gly-Lys, as it would occur at physiological pH = 7.4. The R groups of Ala and Gly are not acidic or basic, therefore do not have a pka and the charge on these R groups is therefore independent of pH. Glu is acidic and Lys is basic, therefore the charge on these amino acids is pH dependent. The pKas are shown below. pKa N-term = 9.0 C-term = 3.5 Glu4.1 Lys = 10.5 2. Draw a circle around the peptide bonds. 3. Label the C-terminus and the N-terminus. 4. What is the overall charge on the peptide at pH 7.4?arrow_forward
