- In the mechanism of replication the O DNA leading strand is read from 3' to 5 O DNA leading strand is read from 5' to 3 O DNA leading strand product is synthesized 3' to 5 O DNA lagging strand is read from 5' to 3 O Only the DNA leading strand is read D Question 18 What factor is used repeatedly for lagging strand DNA replication but not repeatedly for leading strand replication? O ANTP's O DNA polymerase 3 O a parental DNA template O metal ions O a ligaseA 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 O DNA replication will occur much more slowly O Replication will be highly error-prone O Only one DNA strand will be replicatedIf a mutation occurred that prevented single stranded binding proteins from binding, the result would be: O Replication would not be initiated O DNA would be synthesized on the leading strand, but not the lagging strand Replicating would be initiated, DNA would unwind, RNA primers would be laid down, but DNA polymerase would not bind O The newly synthesized RNA would not be able to leave the DNA template Replication would be initiated, but RNA primers would not anneal to the DNA
- Choose all of the true statements about DNA replication in cells. Hint: 2 statements are true. O Prokaryotic chromosomes contain hundreds of origins of replication. Primers are composed of RNA nucleotides that are complementary to the DNA template strand. DNA polymerase proofreads and replaces ALL errors during DNA copying Primers are short DNA sequences which DNA polymerase can bind to. O Eukaryotic chromosomes contain many origins of replication.Replication of DNA takes place in S phase. O True O FalseHow does the process of DNA replication impact mutations in an individual? All DNA replication stops when there is a mutation so the mutation won't hurt the individual O Replication only produces new DNA strands so the old stand with the mutation is destroyed OSince replication keeps the old strands as templates mutations maybe carried into future strand O Mutations are often lost since the cell with die during the replication process if the DNA is muta

It is powered bythe hydrolysis of ATP. Each strand withinthe DNA double helix is used as a template for synthesis of a new strand.
