The statement: "he also showed that the components were linked in the order phosphate-sugar-base." -- should this say, instead, "he also showed that the components were linked by alternating phosphate and sugar components (eg, "phosphate-sugar-phosphate-sugar-phosphate-sugar-phosphate-sugar")."? The base is not in the chain in the true structure, nor was it in his diagrams. -Madeleine 19:36, 12 April 2007 (UTC)[reply]

Oh, I think I get it. It's means the components of a given nucleotide, not the chain. I'll just insert that word into the article. - Madeleine 19:44, 12 April 2007 (UTC)[reply]

he did not discover ribose. this is what The Merck Index says about ribose:

Birthplace

[edit]

I re-added Sagor as his birthplace as found in this article til March. I am however convinced, that his birthplace is Žagarė near Šiauliai in Lithuania. "Žagarė" figures as "Жагоры" on this map and as "Shagory" on this one. The yiddish name is "Zhagar" without a final vowel. Since I have no final proof for my GPM (Google primary research), I leave it as an offer here. --Gf1961 (talk) 06:29, 28 May 2012 (UTC)[reply]
