Question
Chapter 18, Problem 10TYPSS
Summary Introduction
To analyze:
Colonies whose cells might have mutations from the given figure. The sequences must be analyzed for wild type or normal. Predict three types of E.coli colonies found in lactose
Introduction:
The X-gal is a colorless pigment, which can be cleaved by the β-galactosidase enzyme. The pigment is found attached to the galactose. The β-galactosidase enzyme cleaves off the X-gal pigment, which gives a blue-colored appearance.

The following polynucleotide was synthesized and used as a template forpeptide synthesis in a cell-free system from E. coli. …AUAUAUAUAUAUAU…
If the same polynucleotide described is used with a mitochondriaderivedcell-free protein-synthesizing system, the product is …Met–Tyr–Met–Tyr–Met–Tyr…What does this say about differences between the mitochondrial and bacterial codes?
Suppose that the diagram below represents the genomic organization of an enzyme involved in eye pigment production in mice. Within the gene are four exons. Biochemical analysis has revealed that the active site of the enzyme is located in the C terminus of the protein.
-The nucleotide length of each exon and intron is shown.
-The dinucleotide sequence GT represents the 5’ splice site and the dinucleotide sequence AG represents the 3’ splice site. Both the 5’ and the 3’ splice sites must be present for splicing to occur.
Assume that the first and second stop codons are located immediately after the first and second 5’ splice sites, respectively; the third and fourth stop codons are located near the 3’ end of exons 3 and 4, respectively; all these stop codons are in the correct reading frame.
a) draw what the processed mRNA will look like. Include the start codon on the mRNA and label the approximate locations of the 5’ UTR and 3’ UTR on the transcript. (You do not need to add the 5’ CAP…

- Biochemistry: Site-directed mutagenesis, in which individual amino acid residues are replaced with others, is a powerful method to study enzyme mechanisms. In experiments with particular enzyme, various lysine residues were replaced with aspartate, yielding the results summarized in the table below: Enzyme Form: Enzyme Activity (U/mg) Native enzyme: 1,000 U/mg Recombinant Lys 21 to Asp 21: 970 U/mg Recombinant Lys 86 to Asp 86: 100 U/mg Recombinant Lys 101 to Asp 101: 970 U/mg a. What might be inferred about the role of Lys 21, 86, and 101 in the catalytic mechanism of this enzyme? b. Discuss where within the enzyme one might find Lys 21 and 101. Are these residues likely to be evolutionary conserved in this enzyme? Explain c. Is Lys position 86 likely to be evolutionary conserved? Explainarrow_forwardConsider the following DNA sequence, which codes for a short polypeptide: 5'-ATGGGCTTAGCGTAGGTTAGT-3' Determine the mRNA transcript of this sequence. You have to write these sequences from the 5' end to the 3' end and indicate those ends as shown in the original sequence in order to get the full mark. How many amino acids will make up this polypeptide? Determine the first four anticodons that will be used in order to translate this sequence.arrow_forwardAnalyse and interpret the SCAM data in Fig. 1, and make a table (remember to include a legend) to indicate where each amino acid is located (cytoplasm, membrane, periplasm).arrow_forward
- Clary Fray used the pET vector system to express her prokaryotic amylase enzyme. She added peptone into her culture broth of BL21(DE3) Escherichia coli strain to induce protein expression. At the end of the experiment, she discovered that her protein was not expressed. She repeated three more times but her protein of interest was still not produced. (i) (ii) (iii) (iv) (v) Explain the reason why Clary failed to obtain her protein of interest and suggest a solution to troubleshoot this problem. Clary plans to express her protein along with a polyhistidine-tag. Explain the importance of His-tag in protein work. Is DH5a Escherichia coli suitable to propagate the plasmid before protein expression? Besides heat shock method, elaborate another procedure Clary could utilize to transform the recombinant pET vector into the host cell. If her supervisor instructs her to express a gene from gold fish (Carassius auratus), is the expression system she is using now suitable for this experiment?…arrow_forwardA chain of biochemical events is responsible for Aequorea victoria turning green. Firstly, the protein aequorin converts chemical energy into blue light. A second protein, known as GFP (green fluorescent protein), absorbs the light. Aequorin is a 21 kDa protein with a pI of 4.5 that generates blue light from an attached non-protein chromophore. GFP is a 27 kDa protein with a pI of 6.2. In order for it to fluoresce, 3 amino acids undergo a remarkable reaction when they are folded in the right way. Aequorin does not absorb light in the visible range, and GFP absorbs light at 395 nm and 475 nm. 1. Sketch what you would see if you ran a mixture of aequorin and GFP over a size-exclusion column. In your sketch, include absorbance data at 280, 395, and 475 nm.arrow_forwardExplain why they qualify as machines based on their functions and component molecules.arrow_forward
- You plan to synthesize a peptide to be used as a vaccine to treat melanoma, a particularly aggressive form of skin cancer. Normally, gp100, a protein on the surface of melanocytes, activates cell growth when it is bound by its ligand. Activation of the growth pathway depends on the presence of threonine in the ligand. The effective peptide vaccine will mimic the natural ligand, but won’t cause cell growth and division. Below is the sequence of the natural ligand: LDMKTAG In order to ensure your newly designed peptide vaccine does not cause cell growth upon binding, you must substitute the Threonine residue at position 5. What amino acid would you replace it with, bearing in mind that the peptide should still be similar enough to bind to the gp100 protein in the surface of melanocytes. Explain your choice. Your vaccine will be administered as a topical cream, and you require your peptide to have an overall neutral charge in order to be functional. At what pH should you formulate…arrow_forwardYou are working on a protein for a research project. The protein does not express well in prokaryotic expression systems so you decide to try a eukaryotic system, baker’s yeast, instead. As part of the expression system, you add a signal peptide to the protein so that it will be exported through the endomembrane system to the outside of the yeast cell. This makes purifying the protein much simpler. During the purification, you notice that the protein is heavier than it should be during gel filtration chromatography. This is confirmed by SDS-PAGE. What could be the reason that the protein has gained mass when expressed in the eukaryotic system?arrow_forwardConsider the proteins in Figure 1. Assume they are treated with chymotrypsin to cut them into fragments, and then the fragments are separated by gel electrophoresis. What would the fragment patterns look like in the gel for the three different proteins, assuming we can separate polypeptides that differ in size by very small amounts? Complete Figure 2 below to show the location of the uncut polypeptides (- enzyme lanes) and the cut fragments (+ enzyme lanes).arrow_forward
