- Look at the amino acid chart below that the proctor placed on a board at the front of the classroom before asking the students questions. Help Arcel characterize the DNA mutation (HbS) according to its amino acid and position. a The disease is caused by GAG20→GTG20. b The disease is caused by val6→gln6. c The disease is caused by glu6→ val6. d The disease is caused by glu20→ val20.A mixture of amino acids that do not separate sufficiently when a single technique is used can often be separated by two-dimensional chromatography. In this technique, the mixture of amino acids is applied to a piece of filter paper and separated by chromatographic techniques. The paper is then rotated 90°, and the amino acids are further separated by electrophoresis, producing a type of chromatogram called a fingerprint. Identify the spots in the fingerprint obtained from a mixture of Ser, Glu, Leu, His, Met, and Thr.Below is an EMSA showing four different reactions, A-D. In each tube there is some combination of labelled DNA probe, Protein X (the protein you are studying), and an antibody for Protein X. Identify which combination of components are found in each of the four reactions and explain how you determined that based on the molecular interactions being studied and your knowledge of gel electrophoresis. It is possible that multiple lanes have the same component(s). A B C D EMSA
- Given the following Wild Type and Mutated DNA sequences: 1.) Identify where the base pair change occurs (what letters changed?) 2.) For BOTH sequences, write the mRNA strands, define the codon regions (with spaces), and amino acid sequences. 3.) Describe what kind of mutation has occurred (missense, nonsense, or silent), and what effect this may have on the protein. Wild Type DNA Sequence: 3' - CCTCGTTATGTG - 5' Mutated DNA Sequence: 3' - CCTCGTTATTTG - 5'Both protein and DNA are run together in an isoelectric focusing (IEF) electrophoresis using the immobilised pH gradient (IPG) strip with pH range of 4-7. After the electrophoresis and staining, only ONE band is observed on the middle of the IPG strip. The band is a protein band. Briefly explain why only the protein band and NOT the DNA band appear on the IPG strip.A very common molecular biology research method is to analyze cell or tissue homogenates by SDS-polyacrylamide gel electrophoresis and immunoblotting (Western blot). What can we learn about a protein of interest from this type of analysis? More than one answer is correct. Options: Determine the tertiary structure of the protein of interest. Determine or verify the molecular weight of the protein of interest. Compare the levels of the protein of interest in two different cell types. Determine the amino acid sequence from the product ion spectrum. Determine the intracellular binding partners of the protein of interest.
