Hello, so this is a public version of the test that our professor gave out: You are trying to bio-engineer a virus to carry particular genes between human cells. The virus must not only be able to move between cells and copy-and-carry particular genes, but it also should have as […]

1. Do you think the concept of emergence is important in helping us to better understand how biological systems function? Why or whynot? 2. What is a model? Find an example of a model in the secondary literature that applies to a life science topic of interest to you? Write […]

Suppose a primer initiates the replication process in E. Coli and forms a 20bp (base pair) long stretch. Assume an error rate of 2/1000bp in primer that is taking place only in the lagging strand of DNA during replication. How many errors would you expect in the replication of 3800000bp […]

Q. In an experiment you are studying a neuron that receives synaptic inputs from two other neurons: one from neuron A and one from neuron B. Synaptic transmission from neuron A opens Ca2+ channels in the postsynaptic neuron, whereas neuron B opens Cl- channels. Imagine that ECa = +200 mV, […]
