What is the function of DNA polymerase?
Dr. Dre has decided that he wants to cure cancer and so has designed a bunch of compounds to inhibit various enzymes involved in DNA replication. He tests each of the 5 compounds against the enzymatic activity of each of the DNA replication enzymes and records what each one does to work out what they do. He concludes that [ Select ] Compound B Compound E Compound D Compound A Compound C would prevent the replacement of RNA sequences with DNA, while [ Select ] Compound B Compound C Compound D Compound A Compound E would prevent all steps in DNA replication. He predicts that [ Select ] Compound E Compound D Compound B Compound C Compound A would leave the replicated DNA strand as a series of separate DNA fragments, but that [ Select ] Compound A Compound B Compound D Compound E Compound C would lead to the death of the cell upon DNA replication. Finally, he concludes that [ Select ] Compound D Compound C Compound A Compound E Compound B would prevent the formation of both the leading and lagging strands.
