1. A sea urchin egg is used in a voltage clamp experiment; that is, the value of the transmembrane voltage is set by the experimenter, not by the properties of the membrane.The transmembrane voltage is held at +10 mV for one minute. At the end of that timeA. the voltage-gated calcium […]

1. In the replication of ColE1 based plasmids, explain how copy number is normally regulated, and define and explain the consequences of inactivating mutations in: a. ROMb. RNA1c. RNA2d. PCNB…Why might you want to temporarily reduce plasmid copy number in your cloning experiment? 2. Define and explain the basis for […]

1) Describe the different ways to shift the equilibrium to the left for the following reaction: 2 A (s) + 2 BC (aq) –> 2 AB (aq) + C2(g). Justify your answer. ?H = -352 kJ  2) A classmate asks for your help writing an equilibrium expression for the combustion of […]

Question: Assume you have made a collection of mutant fruit flies that aredefective in various aspects of DNA repair. You test each mutantfor its hypersensitivity to three DNA-damaging agents: sunlight,methylnitrosourea (which cause alkation of guanosine),and nitrous acid (which causes deamination of cytosineand conversion to uracil which lead to a mutation and […]
