Step by step
Solved in 2 steps
- Why is the replication of DNA referred to as a semiconservative process? What is the experimental evidence for the semiconservative nature of the process? What experimental results would you expect if replication of DNA were a conservative process?What are the three models of DNA replication? With the aid of illustrations, show how the Meselson Stahl experiment come to the conclusion of one model of DNA replication. Is DNA replication bidirectional? How did you arrive at this conclusion? Explain the bacterial replication model that supports this conclusion.Describe an experiment that lead to the establishment of the fact that DNA replication is semiconservative
- Why is DNA replication called semiconservative?Shown below is a drawing showing the result of an experiment in which an RNA molecule is allowed to mix with genomic DNA that has been denatured by boiling, and the two molecules are allowed to hybridize. The DNA strand is presumed to be the lighter-shaded one on the top. Note that only one strand of DNA is shown. This result was the first evidence for which of the following processes? a Replication b Transcription c Translation d SplicingList at least five properties that DNA polymerases and RNA polymerases have in common. List at least three differences.
- Why is DNA replication is considered a semi-discontinuous process? Explain in detail.You are studying a colony of cells and determine that some of these cells have a mutated DNA polymerase I that results in loss of function of this enzyme. A) What will the effect of the mutation in DNA polymerase I be on DNA replication? In your answer make sure to describe what would be observed in the leading and lagging strand and explain your reasoning. B) Will this mutation in DNA polymerase I have an impact on another step in DNA replication? In your answer make sure to indicate whether DNA replication will be impacted or not. If it is not, explain why. If it is impacted, then describe the step that is impacted and name the molecule or enzyme involved.In both leading and lagging strand synthesis, DNA replication always proceeds in a certain direction. What direction is this? Explain how oligonucleotide primers in the Polymerase Chain Reaction work (PCR)
