多重下拉选择题
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.

Question restatement and option mapping:
- The question presents five dropdown prompts about compounds A–E and asks which compound would produce specific effects during DNA replication. The provided answer sequence is: Compound B for the first blank, Compound E for the second blank, Compound A for the third blank, Compound D for the fourth blank, and Compound C for the fifth blank.
- So, according to the answer key, the selections are:
1) [Select] = Compound B
2) [Select] = Compound E
3) [Select] = Compound A
4) [Select] = Compound D
5) [Select] = Compound C
Option-by-option analysis (why the chosen compound is associated with each described effect):
- First blank: which compound would prevent the replacement of RNA sequences with DNA
- Correct choice (Compound B): Interpreting the key, Compound B is designated to block the step that replaces RNA with DNA. This implies that Compound B inhibits the enzyme or activity responsible for removing RNA primers or RNA segments and substituting them with DNA. If a different compound were chosen, the description would imply inhibition of a diffe......Login to view full explanation登录即可查看完整答案
