Microbiology Chapter 8 Exam Questions with 100% Correct Answers | Verified | Updated What characteristic of DNA allows two connected DNA polymerases to synthesize both the leading and lagging strands? DNA has a helical shape. DNA is double-stranded. DNA is antiparallel. DNA is flexible. - answerDNA is flexible. What is the function of the connector proteins? They enable one parental DNA strand and one newly synthesized DNA strand to be held together. They allow DNA synthesis to occur in the 3' to 5' direction. They link the leading strand DNA polymerase and the lagging strand DNA polymerase together. They produce the Okazaki fragments. - answerThey link the leading strand DNA polymerase and the lagging strand DNA polymerase together. Which DNA strand is synthesized continuously? Leading strand Lagging strand Neither the leading nor the lagging strand is synthesized continuously. The leading and lagging strands are both synthesized continuously. - answerLeading strand Which of the following are terms associated with Okazaki fragments? DNA ligase Lagging strand Discontinuous Lagging strand, DNA ligase, and discontinuous - answerLagging strand, DNA ligase, and discontinuous Why is the DNA synthesis of the lagging strand considered discontinuous? The synthesis is moving in the opposite direction from the replication fork. The lagging strand only requires one primer instead of multiple primers. The lagging strand only produces single-stranded DNA molecules. DNA synthesis on the lagging strand occurs 3' to 5'. - answerThe synthesis is moving in the opposite direction from the replication fork. What is the initial target of RNA polymerase? The promoter The terminator region The template DNA - answerThe promoter RNA polymerase is guided by the coding strand of DNA. RNA strand. template strand of DNA. - answertemplate strand of DNA. RNA that has hydrogen bonded to itself forms a termination protein. terminator sequence. promoter sequence. stem loop. - answerstem loop. How would one increase the concentration of a particular polypeptide in a cell? Increase the level of transcription Increase the concentration of promoters Increase the amount of DNA - answerIncrease the level of transcription During elongation, how is the RNA synthe
