BTW, the better way to title this article would have been just
Polymerase Chain Reaction
.You could then set PCR as a
title2
: docs.ourbigbook.com/#h-title2-argument e.g. starting the article on Web with:{title2=PCR}
The actual text.
The advantage is that then your article would appear at: ourbigbook.com/go/topic/polymerase-chain-reaction where it could be compared with other people's.
All best.
