Which of the following should not be used to disinfect an area that is potentially contaminated with DNA? - Alcohol Why are enzyme solutions always prepared using a buffered solvent at a specific pH? - A buffered solvent is resistant to fluctuations in pH because it is made with a combination of a weak acid and its conjugate base.

how much BSA is needed to prepare 50 mL of 5 mg/ml of BSA (w/v)? - (50 mL)(5 mg,mL) = 250 mg a technician is assigned the task of inserting a gene, LanA, into a plasmid to ultimately be expressed as a therapeutic protein in E coli. label the following steps (1-4) in the correct order the technician must perform them to accomplish her task. - 1) design primers to amplify the lanA sequence using polymerase chain reaction (PCR) and perform the PCR reaction 2) digest and provide lanA PCR p...

explain the difference between a scientific hypothesis, Theory, and law - -Hypothesis: tentative statement about the natural world leading to deductions that can be tested -Theory: well sustain an explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses - Law: descriptive generalization about how some aspect of the natural world behaves under stated circumstances cells produced by mitosis are haploid - false germinat...
