- 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?In E. Coli, which enzyme is responsible for removing and correcting mistake individual nucleotides during replication? O a) DNA Polymerase I b) RNA polymerase III O c) Nuclease d) DNA polymerase IIIWhy is DNA replication called semiconservative?
- The enzyme that proofreads the new strand of DNA, looking for and correcting mistakes as it replicates is called: A) helicase B) DNA polymerase III C) ligase D) RNA polymerase E) primaseIn DNA replication, the enzyme helicase breaks hydrogen bonds between complementary nucleotides and causes the double-stranded DNA to become single-stranded (denatures the DNA). What is used in PCR to break the hydrogen bonds between complementary nucleotides? A) buffers B) DNases C) taq Polymerase D) heat E) helicaseDNA replication is semi-conservative, this statement means that Question 6 options: a) the new DNA molecules that are made are not identical to the original DNA molecule. b) the new DNA molecules that are made are only partially DNA since RNA primers are included. c) the new DNA molecules that are made are composed of one strand of the old DNA molecule and one strand of new DNA. d) of the two new DNA molecules made, one is entirely new DNA and one is entirely old new. e) the new DNA molecules that are made have a mixture of old and new DNA in each strand of the DNA duplex, randomly interspersed.
