[edit] Article's quality

Does it describe Eukaryotic cells or all cells ? Do all cells folow this cycle or are there some exceptions ? -- Taw

I think this is specific only to eucaryotes, but among these, the mechanism is fairly conserved from yeast to man. AttishOculus 22:19, 11 Jun 2005 (UTC)

Is there a reason to have this article separate from Cell division and Mitosis - Marshman 05:46, 30 Sep 2003 (UTC)

Yes. Mitosis is only one small part of the cell cycle. There is more than enough information about mitosis to justify its having its own entry, but it should not be combined with cell cycle. ~mdash; Brim 17:38, Nov 27, 2004 (UTC)

I think this topic would deserve some additional, more detailed information. (exeact transitions, checkpoints, cyclins, CDK's and CKI's in detail etc.) I would be glad to add some more information, regarding the importance of the subject (in cancer research, for example), but as I am only a student, I could use no other source of knowledge but my textbooks, so I would be happy to have an expert look through my work every once in a while.

Additionally, I fear that stacking up the article with scientific info would make the whole article frightening and overwhelming for non-professionals. What would you recommend in order to avoid that? Would having separate sections in the article after the current one as an introduction be sufficient, or would it be better to add a new article "Cell cycle in detail", or just have a number of new pages linked into the main page (eg. "Replication initiation mechanisms")? What would be the general Wikipedia practice in such cases? AttishOculus 22:19, 11 Jun 2005 (UTC)

This article lacks so much info...i mean a lot. I came here looking for help on the topic--because i just couldn't understand some of it, and it wasn't here. All of the stages require info of the cell cycle. The Mitosis part deserves its own part. The cycle's checking system needs its own part. This is one bad article. I'll try to fix it in a day or two after my test. :) Nominaladversary 01:54, 31 March 2006 (UTC)

The mitosis part has its own part at mitosis. I'd bet my boots check points will also direct you to the cycle's checking system too. Aaadddaaammm 07:10, 19 October 2006 (UTC)

[edit] No description of basic process of cell division

There has to be a section dvoted to description of all phases during mitosis (and variations during a meiosis). The article seems to dwell heavily upon recent advances in molecular biology. These advances have to be placed in perspective with the general biology of the cell cycle Nattu 20:21, 16 June 2006 (UTC)

This article is a recent retooling of a rather poor, stubby original. Currently mitosis and meiosis have their own articles, which are in a much better state than this one was; the phases of mitosis also have their own articles. There's an emphasis on molecular biology in the current article because I wrote it :) Feel free to add more general information, as I think in time this article should evolve to be a proper header for Category:Cell cycle.

Yes, the mol bio part is good and we can shape it further. For now, emphasis must be on cell cycle basics and I will contribute my bit to it. Nattu 19:19, 23 June 2006 (UTC)

[edit] Image issues

The current illustration of the cell cycle should be removed or replaced in my opinion. It would almost have been ok if all the phases seemed to have equal duration. But in this illustration S phase is actually smaller than the G2 phase! - HungryHippo 19. july 2006

You're right, it's not really very good, but I do think it's better than nothing (especially given the explanation of its deficiencies in the caption). I've posted a {{reqdiagram}} in the hopes of attracting a good diagram creator, which I am not. Opabinia regalis 02:07, 20 July 2006 (UTC)

[edit] About diploid, haploid and monoploid

"In this quantity of DNA within the cell has increased to 4c, but the cell is still considered diploid." Finally i got the information.

[edit] embryology

Does anyone happen to know any embryologists? I think Embryology really needs a lot of expert attention. would sympathtic editors consider a positive vote here? [1]Slrubenstein | Talk 19:05, 28 August 2006 (UTC)

[edit] Mitosis vs. M phase

As far as I know M phase=Mitosis+Cytokinesis, but there is no article on M phase, only on Mitosis, and in the picture:

Schematic of the cell cycle. I=Interphase, M=Mitosis. The duration of mitosis in relation to the other phases has
been exaggerated in this diagram

, I think, M phase is denoted by letter "M" and not Mitosis, as there are four phases: G1, S, G2 and M (+G0). Should the text below the picture be changed?
