What is a major difference between eukaryotic DNA replication and prokaryotic DN

Question

What is a major difference between eukaryotic DNA replication and prokaryotic DNA replication? a. Prokaryotic replication does not require an enzyme b. Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have multiple origins of replication c. Eukaryotes are bacteria and have no DNA d. Prokaryotes are bacteria and have no DNA Alpha-amanitin is a toxin produced by the death cap mushroom. It blocks the synthesis of mRNA. Why is it deadly to eat death cap mushrooms? a. It would block DNA synthesis b. It would not allow the splicing process c. It would not allow proteins to be made d. It inhibits ribosomes The universal regulatory mechanism in eukaryotes for controlling gene expression includes: a. Control of the processing of mRNA after it is transcribed from DNA but before it leaves the nucleus, and control of the rate it leaves the nucleus b. Control of the genes transcribed and the rate they are transcribed c. Control of mRNA in the cytoplasm after it leaves the nucleus, including changed to mRNA before translation begins d. All of these mechanisms are used; there is no single universal mechanism ___can affect mRNA secondary structure and control translation initiation. a. aptamer b. DNA c. elF1 d. None of the above

Explanation / Answer

7. The answer is: b. Prokaryotic chromosomes have a single origin of replication, while eukaryotic chromosomes have multiple origins of replication.

This is the major difference between eukaryotic and prokaryotic DNA replication.

8. The answer is: c. It would not allow proteins to be made.

Since alpha amanitin inhibits RNA polymerase so mRNA production will not happen as a result of which proteins will not be made.

9. The answer is: d. All of these mechanisms are used; there is no single universal mechanism
