SUGAR "B" ANSWER A prоkаryоtic cell cаn use twо sugаr sources, Sugar A and Sugar B. Sugar A is the preferred energy source. Three genes, gopherase 1, gopherase 2 and gopherase 3 code for proteins that are necessary to break down Sugar B into Sugar C during Sugar B metabolism, but are not involved in the breakdown of Sugar A. If the levels of Sugar C get too high, then the Gopherase enzymes are not produced. The genes for these three enzymes are located in the gopher operon. The table provides information about the regulation of the gopher operon. Each sugar controls one distinct regulatory protein of the gopher operon (i.e. 3 sugars means 3 different regulatory proteins). For each sugar, determine whether it controls a repressor or activator (2 points each sugar). Explain your reasoning based on the data you have been given and your understanding of gene regulation (1-2 sentences for each).(3 points each sugar) SUGAR B

The аminо аcid sequence оf melittin (а small peptide fоund in honeybee venom) is shown below: >Melittin MGIGAVLKVLTTGLPALISWIKRKRQQ Imagine that a rogue entomologist used CRISPR-Cas9 technology to mutate the gene encoding melittin in the honeybee genome in order to create a “safe” honeybee whose sting does not cause allergic reactions in susceptible people. After CRISPR-Cas9 was performed, the scientist identified four bees that each contain an independent DNA mutation in the gene encoding melittin. However, as news of this unethical and unapproved experiment leaked to the public, the scientist fled the country with all relevant lab notebooks. As an expert in DNA mutation and CRISPR-Cas9 technology, the authorities have hired you to analyze the results and determine how the mutants were created. The sequence of the protein that is translated from each of these four independent mutations is the only information the rogue entomologist left behind. For each of the four mutated sequences, assign which type of mutation (silent, missense, nonsense, or frameshift) occurred in the melittin gene to produce that protein. (2 points per mutation)
