1. (14 pts) Central Dogma – DNA to protein questions
   1. Think about the general flow of genetic information in living organisms. Summarize the three steps of the central dogm
   2. Imagine that a DNA section of the gene that codes for the enzyme phosphofructokinase read 3’ – TACTGGCGC-5’ What would be the resulting messenger RNA strand and why?

3. Use the codon chart above to answer this question. From left to right list, the exact amino acid chain that would be formed? (write the amino acids out in order).

4. Imagine that a mutation added an extra base was added at the start of the strand, so the strand now rea 3’-GTACTGGCGC-5’. How would this affect the outcome? Would a chain of amino acids still be created?

5. Imagine, a malfunction occurs in a cell.   The cell is no longer able to regulate the H₃O⁺ levels inside the cell, the amount of H₃O⁺ increases. Note you will have to call back on information from previous chapters (Ch 3, Ch 5) to answer this
   1. What would happen to the pH? Explain
   2. Which part of the central dogma steps would be most affected and why?
6. Why do genes code to make proteins, why don’t genes code to make carbohydrates, or fats, or nucleic acids? How do the proteins function in the body?
7. Imagine that a mutation occurred in the last codon in the DNA sequence from part B. Instead of 3’ – TACTGGCGC-5’ the DNA read 3’ – TACTGGTGC-5’.
   1. How would the amino acid sequence change? Explain how the mutation would or would not have an effect on the function of phosphofructokinase. You will need specific details relating to the chemistry of the molecules.
   2. How and why would a change in phosphofructokinase impact the health of the person with this mutation? Explain in details

You've decided to build a radio to listen to your favourite FM radio station, which broadcasts at 102.9 MHz. For the tuner, you'll be using an RLC circuit, but the only inductor you happen to have on hand has a value of 0.870 μH.

Unfortunately, there's another radio station — which you don't want to listen to — at a nearby frequency of 103.3 MHz. To prevent any interference from this 103.3 MHz radio station, you want the peak current from it to be no more than 0.160% of the peak current from your favourite 102.9 MHz station. What value of resistor should you use in your RLC circuit? (Assume the two stations have the same strength.)

Hint:You'll have to first calculate the value of the capacitor so that the radio tunes to 102.9 MHz.
