A DNA polymerase has everything it needs for extension, EXCEPT for RNA primers. What is the most likely consequence of this? No DNA replication will occur at all DNA replication will occur much more slowly Replication will be highly error-prone O Only one DNA strand will be replicated

Which of the following statements is/are TRUE for DNA Replication? Two daughter DNAs are formed, each one contains an old and new strands. When the (parent) DNA strands unwind, the 3'→ 5' strand is the leading strand while the 5'→3' strand is the lagging strand. Requires dATP, dTTP, dGTP, dCTP and Mg2+ The replisome is the biological machine responsible in replicating DNA.

If a cell has trouble unwinding the DNA and relieving strain far ahead of the replication fork, in which of the following genes is there a mutation? Beve reverse transcriptase O gyrases/topoisomerases O single stranded binding proteins O ligase O helicase

Which of the following DNA repair mechanisms involves the 3' to 5' exonuciease function of DNA polymerase? mismatch repair postreplication repair SOS response DNA proofreading base excision repair

Guanine was oxidized into 8-oxoguanine, which process below will ensure the integrity of the DNA? O Oxidative demethylation O Nucleotide-excision repair OSOS response O Base-excision repair

How is bacterial DNA replication different from eukaryotic DNA replication?     Multiple Choice   The result of bacterial DNA replication is two new double stranded DNA molecules that each contain a template strand and a newly synthesized strand, while the result of eukaryotic DNA replication is one newly synthesized double stranded DNA molecule and one DNA molecule that was the original template.   Bacterial DNA replication involves nucleotides that are not found in eukaryotic DNA replication.   Bacterial DNA replication moves out from the origin of replication in two directions, while eukaryotic DNA replication moves out from the origin of replication in only one direction.   Bacterial DNA replication only replicates small pieces of the chromosome, while eukaryotic DNA replication replicates the entire chromosome.   Bacterial DNA replication begins at a single location on the chromosome, while eukaryotic DNA replication begins in many places dispersed throughout each…

What will be the outcome for any resulting protein from this this DNA segment  

The SOS response in bacteria is a type of repair that only occurs under extreme conditions when DNA is heavily damaged and not normally used since it can cause replication errors when repairing the DNA. O True False

Which of the following replication proteins is incorrectly paired with it’s function?     DNA polymerase - adds nucleotides to the growing strand     Single stranded binding proteins - hold the DNA strands apart while they are being replicated     Ligase - enhances separation of DNA strands     Topoisomerase - relieves torsional stress due to unwinding by the DNA     Primase - synthesizes a short RNA sequence to initiate replication
