Eukaryotes and Prokaryotes[change source]

I don't know, is it relevant/should it be pointed out that Eukaryotes (the organisms behind the cells with a nucleus) do have chromosomes, while Prokaryotes (Bacteria,...?) do not? - It is hinted at in the text, would "mentioning" it do any good? --Eptalon (talk) 22:12, 9 December 2009 (UTC)

Interesting question. It was once thought that bacteria had their DNA naked, but apparently it does have some protein wrapped up with it. Of course, that's not the same kind of chromosome as eukaryotes, but it makes any simple statement not quite accurate. I settled for the 'all nuclei have chromosomes' formula because it is accurate, and only eukaryotes have nuclei. It also covers those cases like mammalian red blood cell, which lose their nuclei. I'll add something about eukaryotes. Macdonald-ross (talk) 10:39, 10 December 2009 (UTC)

This artitle seems to be comparatively small to me. The german aricle offers a lot of information, and way more detailled than this article.

How about signing your comments? On your point, we are not trying to compete on quantity, but there is more information on other pages: Genetics#Between Mendel and modern genetics, Karyotype and cell division. Macdonald-ross (talk) 03:45, 15 February 2012 (UTC)
