The mutagen EMS converts guanine (G) to O-6-ethylguanine (G*). O-6-ethylguanine (G*) forms base pairs with thymine (T) instead of cytosine (C). Suppose that exposure to EMS damages a DNA molecule as shown below: 
a. Diagram the steps required for the incorporated G* to induce a stably inherited mutation. Your diagram should include all necessary rounds of replication.
b. Characterize the mutation induced by EMS as a transition, transversion, or frameshift.
