Comments P.3 right column 6th paragraph:"Now consider a typical intron-free eukaryotic gene. The average lengths of eukaryotic proteins are ∼50% longer than those in bacteria (BNID 112126), and eukaryotic transcripts harbor 5′ and 3′ UTRs with average respective lengths of ∼150 and ∼350 bp (primary source), so a 2-kb transcript length is a reasonable baseline value."
