Researchers have designed a graphene field-effect transistor, where graphene-oxide is used as the transistor channel between the source and drain electrodes. Explain how such a sensor configuration could be used to detect the presence of specific single stranded DNA molecules in the solution. Explain how the same measurement could be performed with an amperometric biosensor, taking care to specify the difference between the two types of electrochemical sensors.

Enzyme X has a molecular weight of 48,000. It converts substrate Z into product Y. Z absorbs at 340 nm, and Y absorbs at 480 nm. A.) At what wavelength would you measure the change in absorbance to assay for enzyme X? Would the absorbance increase or decrease over time? B.)If Vmax = 60 μmol/min and you used 400 μL of a 0.1 mg/mL solution of enzyme, what is the turnover number?
You study actin polymerization by monitoring the increase in fluorescence of pyrene-labeled actin. Pyrene is a fluorescent molecule, which has very low level of fluorescence on its own or when fused to G-actin. However, the pyrene fluorescence increases dramatically when pyrene-labeled G-actin is incorporated into a polymer. In this assay, the amount of pyrene fluorescence is proportional to the amount of actin polymer. In the figure below, actin polymerization curves resulted for conditions listed below; assume that G-actin concentration is above the critical concentration for the pointed end and that ATP is present. Which curve corresponds to which condition? Explain

Cone snails are carnivores that inject a powerful set of toxins into their prey, leading to rapid paralysis. Many of these toxins are found to bind to specific ionchannel proteins. Why are such molecules so toxic? How might such toxins be useful for biochemical studies?
This lab examines the relationship between the absorbance of light by a solution at 595 nm and the concentration of the Coomassie Blue dye-BSA protein complex in the solution. State whether the following descriptions of the lab experiment are valid or not, and explain why you say Yes or No: a.The experiment would be significantly more accurate if absorbance readings were recorded for a range of wavelengths, not just for 595 nm.b.The experiment has limited accuracy because it does not account for the absorbance of light by the other components (components that are not the dye-protein complex, such as excess dye that is not bound to any protein) of the solution.c.The absorbance reading measures practically all the protein content in the solutions
Suppose that you are tasked to determine the protein concentration of an unknown protein solution via Bradford assay. You prepared six solutions of bovine serum albumin (BSA) with different concentrations. The initial concentration of the BSA stock solution is 7.50 mg/mL. Approximately 200 µL of Bradford Reagent was added to each of these solutions and the absorbance at 595 nm was taken after 5 minutes. See the table below for data on the standard solutions. Standard # A595 BSA conc (mg/mL) 0.000 0.158 2 1.125 0.291 2.250 0.372 4 3.375 0.503 5 4.500 6 5.625 0.675 Determine the protein concentration, in mg/mL, of the unknown solution if its absorbance at 595 nm was 0.248. Note: Final answer format must be x.xx (two decimal places). Round off only in the final answer. Do not round off in the middle of calculation.

Which sensor, when it comes to sensitivity, will be favoured as a biosensor, the one with great sensitivity or the one with low sensitivity? Justify your position using examples.
Chemistry You have constructed a standard curve from BSA protein for a Bradford Assay. The curve has 0, 1, 2, 3, and 4 ug protein in 50 µl water. You have an unknown protein with concentration somewhere between 1-5 mg/mL. What serial dilution series should you use to guarantee at least two dilutions of your unknown fall below 3 ug (linear portion) on the standard curve? For example, would 1/2 x 1/2 x 1/2 (3 2-fold dilutions) be sufficiently dilute that two of the dilutions would give values within the linear portion of the standard curve?
