Hello, I'm P,TO 19104. I noticed that you added or changed content in an article, DNA extraction, but you didn't provide a reliable source. It's been removed and archived in the page history for now, but if you'd like to include a citation and re-add it, please do so. You can have a look at the tutorial on citing sources. If you think I made a mistake, you can leave me a message on my talk page.   P,TO 19104 (talk) (contribs) 21:55, 7 February 2021 (UTC)

Copying licensed material requires attribution
Hi. I see in a recent addition to DNA extraction you included material from a webpage that is available under a compatible Creative Commons Licence. That's okay, but you have to give attribution so that our readers are made aware that you copied the prose rather than wrote it yourself. I've added the attribution for this particular instance. Please make sure that you follow this licensing requirement when copying from compatibly-licensed material in the future. — Diannaa (talk) 10:20, 8 February 2021 (UTC)
