Is there any particular reason you link to Wikiwand instead of https://en.wikipedia.org/wiki/Oscillating_gene ? The content appears to be the same.

No. I think the wikiwand site looks nicer so my browser is set to auto redirect. For me, that's just how wikipedia looks now, so I forget that posting those links will look weird and sometime dodgy to other people.
