1,00 bases per second

10 bases per second

10,000 bases per second

randomly on the chromosome

at the promoter

at any stretch of DNA that is high in AT pairs

always at the same place

Single-stranded binding proteins

DNA polymerases

Topoisomerases

Helicases

eukaryotic DNA is always single stranded

the eukaryotic replication machinery is 1000 times faster than the prokaryotes

the eukaryotes have more amount of DNA for replication

each chromosome contains multiple replicons

Occurs only when λ phase has infected E. coli

It occurs in bidirectional manner

It occurs in a unidirectional manner

Always uses T7 DNA polymerase when infected by T7 phage

occurs after the synthesis has been completed

requires the presence of an enzyme separate from the DNA polymerases

occurs in prokaryotes but not eukaryotes

is a function of the 3'-5' exonuclease activity of the DNA polymerases
