The actual synthesis of DNA in E. coli is carried out by the function of Polymerase III, which is a complex containing (list below) nucleic acid. By convention, the sequence of bases in DNA is expressed in the 5' to 3' direction. The discovery of Okazaki fragments suggested that DNA synthesis occurs in short fragments. DNA polymerase uses nucleoside triphosphate to form a phosphodiester linkage to the free hydroxyl group on the 3' end of the DNA strand it is synthesizing. Circle the correct answer: TRUE FALSE Both strands of DNA serve as templates concurrently to maintain the fidelity of DNA synthesis. The function of the proofreading activity is to ensure accuracy. Which of the following possesses both 5' to 3' and 3' to 5' exonuclease activity? Why is an RNA primer considered essential during DNA synthesis by DNA polymerase III? All of the following properties or characteristics are possessed by telomeres except: 21. Telomeres have the ability to prevent the loss of genetic information. 22. List the steps in the model of E. coli recombination.
Okazaki fragments are: a. The remnants of the original strands that are dispersed in the new double strand DNA molecules. b. RNA primers used for DNA replication. c. Ring forms of DNA polymerase. d. Short DNA pieces that explain how DNA is synthesized on the lagging strand. e. Short DNA pieces that explain how DNA is synthesized on the leading strand.
