Choose all of the true statements about DNA replication in cells. Hint: 2 statements are true. Prokaryotic chromosomes contain hundreds of origins of replication. Primers are composed of RNA nucleotides that are complementary to the DNA template strand. O DNA polymerase proofreads and replaces ALL errors during DNA copying. Primers are short DNA sequences which DNA polymerase can bind to. Eukaryotic chromosomes contain many origins of replication.

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.

Arrange the steps of DNA replication in the order that they occur. First step Helicase unwinds the DNA double helix. Last step Answer Bank DNA polymerase synthesizes DNA. RNA primers are added. DNA ligase joins DNA fragments together. RNA primers are removed. Single-stranded DNA-binding proteins bind to each template strand.

Describe the structure of a bacterial genome, and explain how it differs from a eukaryotic genome. Explain what a plasmid is, and describe the role of plasmids in the spread of antibiotic resistance genes. Explain how bidirectional semiconservative DNA replication copies the circular chromosome of a bacterium during cell division. Explain the steps of replication by DNA polymerase, including initiation, elongation, and termination. Explain the different kinds of mutations and how they occur.

Which of the following is matched correctly? DNA helicase: unwinds DNA prior to transcription DNA polymerase: adds RNA nucleotides during transcription DNA polymerase: adds DNA nucleotides during replication RNA polymerase: adds RNA nucleotides during translation All of the above are correctly matched

Rank from the first to the last steps in DNA synthesis. Reset H DNA polymerase DNA strands separate as the enzyme helicase unwinds them DNA polymerase catalyzes the covalent addition of free nuclectides to the growing new DNA strands The enzyme primase builds ANA primers on the existing DNA strands Two identical doutle helices First Last

Why is an RNA primer necessary for DNA replication?     The RNA primer is necessary for the activity of DNA ligase.     The RNA primer creates the 5â and 3â ends of the strand.     DNA polymerase can only add nucleotides to RNA molecules.     DNA polymerase can only add nucleotides to an existing strand.

When you have prokaryotic replication, there is a short window (1-2 min.) where one strand of the DNA is not methylated (the DNA is hemi-methylated). This could help DNA repair mechanisms to know which strand are old or new. They could repair the new one with the old one as a guide. True False
