If a gene for a polypeptide has a mutation that causes an amino acid change but the new amino acid has very similar properties (e.g. non-polar amino acid substituted for another non-polar amino acid), then it is likely this mutation will have no effect on th function of the protein and will be termed a neutral mutation. O True O False

Figure out the mutation. You will need the codon table for this question. WT genomic sequence of a really small gene and matching complete amino acid sequence of its gene product. GGT ATG GGG ACT TTG AGG ATG ATA AGG CGT AAA TAA ATAT Met Gly Thr Leu Arg Met Ile Arg Arg Lys A mutant is found that has the following protein sequence: Met Gly Thr Leu Arg Gly. What is the likely mutation? between T14 and G15, insert T. G7 -> del. T5 -> del. G29, T30, A31 -> del between T14 and G15, insert AA. A31 -> T. C11 -> del

Draw the molecular formula of the covalently modifi ed histone side chain of acetyllysine. How does this modifi cation alter the chemical properties of the side chain?

Given the following diagram of how protein AWESOME1 binds to it's target DNA, describe the potential effects of each of the 5 mutations shown below. The wild-type sequence of a helix #1 is also shown in the blue box, and all the mutations are in helix #1 (see numbers for identifying particular residues). a helix #1 R(1)-V-I-L-Y-F-W-I-M-Y-F-S-H-Y-W-R(16) #1 Predict the consequence of the following mutations: 1) Arg(1) to Glu 2) Arg(1) to Ala 3) Phe(6) to lle 4) Trp(7) to Phe 5) Met(9) to Pro in
