Most bacteria can easily be lysed by heating to a high temperature, thus eliminating the need for a separate DNA extraction step prior to DNA amplification by PCR. Probiotic bacteria are notoriously difficult to lyse, requiring enzymatic or physical disruption methods. Explain why (think about gram identity and the environmental conditions for probiotic bacteria).

Eukaryotic cells also require DNA extraction steps, unlike most bacteria. Explain why (think about the differences in cell structure).

Many DNA extraction protocols include a step where DNA is precipitated from solution, thus enabling the isolation of pure DNA. This step involves the addition of salt and alcohol. Explain why the addition of salt and ethanol causes DNA to precipitate from an aqueous solution. (Think about the structure of DNA and its interaction with an aqueous solvent).

Motorcycle riders wear high visibility clothing so that drivers can spot them easily. 50% of Motorcyclist wear high visibility clothing. A researcher experiments and determines that if drivers see a Motorcyclist, then the probability the Motorcyclist was wearing high visibility clothing was 0.51. That experiment shows that 92% of Motorcyclist were seen by drivers on the road. A. Find the probability that a driver does not see a Motorcyclist , give that the Motorcyclist was wearing visibility clothing? B. Find...

Some monkey flowers (Mimulus guttatus) living near the sites of copper mines can grow in soil containing high concentrations of copper, which is toxic to most plants.

Some monkey flowers (Mimulus guttatus) living near the sites of copper mines can grow in soil containing high concentrations of copper, which is toxic to most plants. Copper tolerance is a heritable trait. The map below shows the area near an old copper mine, which contaminated the nearby soil with copper. A stream flows past the mine toward the lake at the bottom right of the map. Use the map to determine which of the statements below are true. Select...
