Hi all, 

To my knowledge, the error rate of Taq is said to be 1/1000 , 
that of proofreading Pols (Pwo, Pfu) ist said to be 1/5000.

Are these figures close to reality and what do they actually 
mean? When I copy a gene with Taq, 
there will be (statistically) 1 error in every 1000 bases? 
Meaning that after a 30 cycle (theoretical) PCR starting from a 
single copy, there should be 30 errors within 1000 bp (after 
30 duplications)?
