Dna Replication Ppt Pdf. Dna replication what are the key events of the template model for dna replication. In cooperation with ssb this.
Oric 245 bp 3 13 nt and dnaa binding sites in 4 8 m bp genome. Dna helicase allows for processive unwinding of dna. Unwinding of dna the interaction of proteins with ori defines the start site of replication and provides a short region of ssdna essential for initiation of synthesis of the nascent dna strand.
Regardless of organism replication origins are unique dna segments with multiple short repeats recognized by multimeric origin binding proteins and usually contain an a t rich stretch.
Unwinding of dna the interaction of proteins with ori defines the start site of replication and provides a short region of ssdna essential for initiation of synthesis of the nascent dna strand. Origin of replication in e. In cooperation with ssb this. Helicase unwinds the double helix the two exposed strands of dna act as a template for dna replication dna polymerase adds the correct complimentary base pairs to the exposed strands.
