Talk:RNase H-dependent PCR

I am curious when the tag for needing citations can be removed. When it was added, tehre was only one citation. Now there are four, all to published journal papers. More can be added, if necessary. What is the general requirement for a Wikipedia article like this? — Preceding unsigned comment added by Jdobosy (talk • contribs) 16:00, 20 November 2017 (UTC)
