Would you expect DNA polymerase or RNA polymerase to have a higher fidelity (accuracy)rate? Why?
A)DNA polymerase has a lower fidelity rate than RNA polymerase.DNA replication can tolerate many errors.By comparison,aberrant RNA molecules can less easily be degraded and replaced with new,correct RNA molecules.
B)DNA polymerase has a higher fidelity rate than RNA polymerase.DNA replication cannot tolerate many errors.By comparison,aberrant RNA molecules can easily be degraded and replaced with new,correct RNA molecules.
C)DNA polymerase has the same fidelity rate compared to RNA polymerase.DNA replication cannot tolerate many errors but neither can RNA replication.

DNA polymerase has a higher fidelity rate than RNA polymerase because DNA replication cannot tolerate many errors. The information encoded in DNA is crucial for the proper functioning of cells and errors in replication can lead to mutations that may result in disease. In contrast, aberrant RNA molecules can easily be degraded and replaced with new, correct RNA molecules. RNA polymerase can make errors in transcribing RNA, but the impact of these errors is generally less severe compared to mutations in DNA.
