CHAPTER 5 DNA REPLICATION I: Enzymes and mechanism
accurate and complete replication of the DNA is essential to the ability of a cell organism to reproduce In this chapter and the next we will examine the process of replication After describing the basic mechanism of DNA replication we discuss the various techniques researchers have used to achieve a more complete understanding of replication |

DNA REPLICATION REPAIR AND RECOMBINATION
DNA REPLICATION MECHANISMS All organisms must duplicate their DNA with extraordinary accuracy before each cell division In this section we explore how an elaborate “replication machine” achieves this accuracy while duplicating DNA at rates as high as 1000 nucleotides per second Base-Pairing Underlies DNA Replication and DNA Repair |

DNA Replication
Goal To understand the chemistry of DNA synthesis and how DNA is replicated with high accuracy Objectives After this chapter you should be able to describe the experiment that proved that DNA replication is semi-conservative diagram the reaction for phosphodiester bond formation explain the energetics of DNA synthesis |

DNA replication
Process of DNA duplicating itself Begins with the unwinding of the double helix to expose the bases in each strand of DNA Each unpaired nucleotide will attract a complementary nucleotide from the medium will form base pairing via hydrogen bonding Enzymes link the aligned nucleotides by phosphodiester bonds to form a continuous strand |

How long does DNA replication take?
In mammalian cells, the replication of DNA in the region between one replica-tion origin and the next should normally require only about an hour to com-plete, given the rate at which a replication fork moves and the largest distances measured between the replication origins in a replication unit.
How does a replication fork move in E coli?
Summary of replication fork movement in E. coli. Helicases such as DnaB and PriA unwind the parental duplex, and SSB stabilizes the single strands. Topoisomerases provide a swivel to prevent an excessive accumulation of supercoils in the DNA.
What is a replication fork?
The region of replicating DNA at which the two strands of the parental DNA are separated and two new daughter DNA molecules are made, each with one parental strand and one newly synthesized strand, is called a replication fork.
