Part A: Bacteria and other microbes can be used to "clean up" an oil spill by breaking down oil into carbon dioxide and water. Two samples isolated from the Deepwater Horizon leak in the Gulf of Mexico were labeled A and B. The DNA of each was isolated and the percent thymine measured in each sample. Sample A contains 21.5% thymine and sample B contains 27.5% thymine. Assume the organisms contain normal double stranded DNA and predict the composition of the other bases.

Part B: Both samples are then denatured to remove the secondary structure. Which will have the higher temperature to denature? B or A

If you were to genetically engineer a bacterium to clean up (bioremediate) an oil spill in the ocean, what features would you give this bacterium to enable it to grow and divide effectively in this environment, to metabolize the pollutants and to tolerate any environmental stressors that it would be exposed to?

The BP spill is projected to cost over $40 billion to clean up, and the Exxon Valdez tanker spill of decades past has rung up a reported $4 billion tab. One would think that incident prevention should be top priority with all proponents, that preventing incidents would be a key strategy to stay solvent. So why is it that executive management and shareholders often dodge the zero-tolerance approach to environmental risk? Are regulations limiting liability of firms encourage risk taking...

The comammox bacteria play a role in nitrification and therefore in the nitrogen cycle. Other microbes, with distinct ecological niches, also participate in the nitrogen cycle. The metabolic reactions involving nitrogen that bacteria perform include: nitrogen fixation (N2 → NH3), nitrification (NH3 → NO3- or NO2-), and denitrification (NO3- or NO2- → NO, N2O, and N2), all of which make up the nitrogen cycle. Each of these reactions is carried out by a unique set of microorganisms with a distinct...

Lab Intermolecular Forces: Cleaning Up an Oil Spill Option 1 – Chemical Agents: To speed the process of oil removal from the ocean interface, researchers use oil dispersants or surfactants, (specialized chemical agents) to break up the spill. These chemical function in the same way that dish soap functions when we wish to break up grease/oil when washing dirty dishes. Basically, these chemicals work to mix oil and water better than normally possible so that the oil sinks deeper into...
