Name the bacterial enzyme that takes over new strand synthesis in replication after the primer is formed. Please include any number that is applicable. DNA polymerase omega DNA polymerase II DNA Polymerase epsilon DNA polymerase delta O DNA Polymerase I

The enzymatic activity of prokaryotic DNA polymerases is faster than that of eukaryotic DNA polymerases, but the overall rate of DNA replication is faster in eukaryotes than prokaryotes.  How is this possible?  Group of answer choices Prokaryotic but not eukaryotic DNA replication requires a primer. Eukaryotic but not prokaryotic DNA replication proceeds from multiple origins. Prokaryotic DNA replication is a more complex process, with time-consuming polymerase switching that is not needed in eukaryotes. Prokaryotic but not eukaryotic DNA replication proceeds from both 5’ --> 3’ and 3’ --> 5’ Prokaryotic DNA polymerases and not eukaryotic polymerases have proofreading ability.

What are the differences between In vitro and In vivo DNA replication?  Please answer at your own words.

Drag and drop the following terms into the correct spots on the image below. 1. Amino Acids 2. Codon 3. mRNA 4. Ribosome 5. tRNA

What enzymes are required for the initiation of replication in eukaryotes? Are these complexes the same or different in prokaryotes? Answer in 2-3 sentences.

______________ is a kind of spontaneous mutation that results from a short-term, reversible phenomenon that leads to abnormal base pairing during DNA replications, followed by another round of DNA replication which results in one of the two daughter DNA molecules containing a point mutation. Group of answer choices Tautomeric shift Frameshift mutation Nonsense mutation Pyrimidine dimer Conditional mutation
