what do you need for DNA replication in prokaryotes

primer with free OH group at 3' end
template DNA
dNTPs
Mg

DNA ligase

closes the nicks in DNA in lagging strand

11

Robert lehman

ligase

12

helicase

14

dnaC

loader of helicase

15

dnaG

primase produces RNA primer

16

primers

used to iniate DNA synthesis

topoisomerase

release torsional stress

20

primosome

responsible for primer synthesis

21

repliosome

responsible for replication at each fork

22

telomeres

protects chromosome ends from being degraded
