Depurination of purine bases results in an apurinic site. assume a single depurination event occurs in the gc base pair of the sequence below and is not repaired. then, if two rounds of replication occur, which of the following dna sequences will exist after two rounds of replication? remember that when dna polymerases encounter an apurinic site, most often an a is incorporated into the newly synthesized strand. assume this is true for the sequence below.

List two new traits (structural or behavioral) that each new species of rat might demonstrate as it adapts to the conditions on two of the four islands. choose only two islands that are described in the lesson. record the island latter and the major habitat feature of the island. then list two new traits each rat subspecies might demonstrate in order to survive the habitat on that island. note: new traits should be unique to that island and be in response to that island’s habitat feature. i cannot remember islands that were names in the lesson so only answer if you have done the lesson (5.13 life science 7b) choose 2 of the islands and describe a structural and a behavioral trait for a rat on each island so 4 total answers, 2 different structurals and 2 different behaviorals, one for each rat for each island
