Comments Supplementary Materials p.2 left column top paragraph:"Assuming Lof [Length of Okazaki Fragment] ~1500 bp for bacteria [BNID 110937, 102051] and 165 bp for eukaryotes [BNID 112149], and noting that RNA primers are on the order of 10 bp in both groups [primary sources], the expected costs of chain elongation for a gene of length Lg are then 0.32 LgPs in bacteria and 2.9 LgPs in eukaryotes." Ps=phosphate bonds hydrolyzed
