Figure 14.14 You isolate a cell strain in which the joining of Okazaki fragments is impaired and suspect that a mutation has occurred in an enzyme found at the replication fork. Which enzyme is most likely to be mutated?
The following diagram represents a DNA molecule that is undergoing replication. Draw in the strands of newly synthesized DNA and identify (a) the polarity of the newly synthesized strands, (b) the leading and lagging strands, (c) Okazaki fragments, and (d) RNA primers.
The diagram shows a model of DNA replication. The diagram points out a number of enzymes and protein factors involved in the process. If this cell were cancerous, a doctor might be using a chemotherapy drug to prevent the replication process from taking place. One such drug, topotecan, inhibits the topoisomerase enzyme from working. Based on the model, if topotecan is used, how will this affect the replication process? A: The hydrogen bonds between the bases will not break B: The double helix of the DNA molecule will not unwind C: It will prevent the addition if complementary nitrogen bases to the leading or lagging DNA strands D: It will prevent the addition of nitrogen bases due to instability of the single-stranded DNA chains

atthew Meselson and Franklin Stahl performed an experiment using heavy isotopes and bacteria to determine which model DNA follows to replicate. Their results are evidence supporting which DNA replication model below? a. The parent DNA molecule is broken into its singular nucleotides from which new nucleotides are copied and then all nucleotides to come back together as one larger DNA molecule. b. The parent DNA strands re-associate after acting as replication templates, forming one molecule of parental DNA and one molecule of daughter DNA. c. The parent DNA is mixed into each of the daughter strands such that both daughter molecules contain a mix of parental and new DNA in each complementary strand. d. The parent DNA strands separate and act as templates for new strands to build onto, such that each resulting molecule is a hybrid of 1 parental strand and 1 daughter strand.
