A) B) C) D) initiation of DNA synthesis Okazaki fragment synthesis leading-strand elongation lagging-strand completion 12. What part of the DNA replication process would be most directly affected in the absence of single-strand binding protein? A) B) initiation of DNA synthesis Okazaki fragment synthesis leading strand elongatin D) lagging-strand completion 13. What part of the DNA replication process would be most directly affected if a strain of bacteria lacking DNA ligase were used to make the cell extracts? A) B) C) leading-strand elongation D) lagging-strand completion initiation of DNA synthesis Okazaki fragment synthesis 14. DNA polymerases are processive, which means that they remain tightly associated with the template stran while moving rapidly and adding nucleotides to the growing daughter strand. Which piece of the replicatic machinery accounts for this characteristic? A) helicase B) sliding clamp C) D) primase single-strand binding protein B) The sliding clamp is loaded once on each DNA strand, where it remains associated until replica ) ) Indicate whether the following statements are true or false. A) Primase is needed to initiate DNA replication on both the leading strand and the lagging strand. complete Telomerase is a DNA polymerase that carries its own RNA molecule to use as a primer at the en lagging strand. Primase requires a proofreading function that ensures there are no errors in the RNA primers used replication.
