Mitosis vs Meiosis[edit]

It might be helpful to link to here in the external links section

Lol the link doesn't even work anymore. should delete but im lazy Elitematterman (talk) 17:07, 5 April 2019 (UTC)Reply[reply]


Something is wrong with the timeline near the end of the article !

Cell Division

Mitosis for body growth and repair result in 2 new cell each with the same as the original cell called daughter cells.

Meiosis for producing gametes(sex cells) result in 4 new cells each with half the number of chromosomes as the original cell —Preceding unsigned comment added by (talk) 07:29, 2 March 2009 (UTC)Reply[reply]

External link suggestion[edit]

I suggest to include this external link:

GA Reassessment[edit]

This discussion is transcluded from Talk:Mitosis/GA1. The edit link for this section can be used to add comments to the reassessment.

I'll be reviewing this articles as part of the GA Sweeps process. Upon looking at the article, here are the major issues I see:

  • One cleanup banner. The problem needs to be solved and the banner removed.
  • Incorrect dash usage. See WP:DASH for when to use a dash, compared to endash or emdash.
  • Quite a few paragraphs with inadequate or absolutely no inline citations.

After these main issues are fixed, I'll give some more specific suggestions. The article will remain on hold for seven days for improvement. Nikki311 23:18, 16 August 2009 (UTC)Reply[reply]

The seven days are up, so I am delisting this article for lack of progress. Thanks. Nikki311 17:26, 23 August 2009 (UTC)Reply[reply]


...redirects here. The word does not even appear on the page at all (verified easily by searching for the text on the page using Firefox). I was going to do my research here, but I am going elsewhere today. Bob the Wikipedian (talkcontribs) 17:21, 5 November 2009 (UTC)Reply[reply]


{{editsemiprotected}} to the authority: please add Bulgarian language in the list. Thank you. There are also other pages which exist but have no connection with the Bulgarian version —Preceding unsigned comment added by Deteto (talkcontribs) 13:15, 18 December 2009 (UTC)Reply[reply]

Question: What is the name of the title for the equivalent article to Mitosis on the Bulgarian language Wikipedia? That needs to be known before making the change. What other articles don't have links to the Bulgarian language articles that can be added? If those pages aren't protected or semi-protected like this one, you can add them yourself, as described at Help:Interlanguage links.
Also, there is no "authority" for handling your request. Any autoconfirmed user, like myself, can make the change. --Mysdaao talk 13:33, 18 December 2009 (UTC)Reply[reply]
Done on this page per request below. If there are any other pages where an interlanguage link to a Bulgarian page can be added, please add them yourself or place {{editsemiprotected}} on the talk page if it is semi-protected. --Mysdaao talk 14:25, 18 December 2009 (UTC)Reply[reply]

Was it only recently recognized? I wonder why there is only the page at EnWiki and not another wikis and.. seem to be no mention at German Wiki. --CopperKettle 19:44, 1 January 2010 (UTC)Reply[reply]


The article states that cytokenisis divides the nucleus, organelles and membrane.

This is wrong. Cytokenisis only divides the cytoplasm. Alexanderblake (talk) 22:59, 3 November 2010 (UTC)Reply[reply]

This is true. Many organelles have their own process of division, which should be mentioned in the article. Graft | talk 20:09, 17 February 2011 (UTC)Reply[reply]

Video clip[edit]

Mitosis 200*150

I have generated a short video clip (about 6 MB / 60 secs) showing the prime phases of mitosis. Please make comments / suggestions as to any usefulness / improvement. --Cookatoo.ergo.ZooM (talk) 17:00, 21 November 2010 (UTC)Reply[reply]

History and terminology[edit]

Mitosis literally means (parallel) warp-thread process, coined by Walther Flemming in 1882, because of the appearance of "chromatin threads in early stages". [1] Was that the first discovery of the process? And which stage exactly was the naming referring to (early anaphase?), specifically (since chromatin probably just meant anything he could see using his dye) is it in reference to the arrangement of the chromosomes or of the microtubules or whatever that will pull them apart? (Meanwhile, the oft-confused meiosis literally means "lessening", appropriately.)

Also, from the article: Each sister chromatid is not considered a chromosome in itself, and a chromosome always contains two sister chromatids. What does this mean? Is it implying that the article's prior discussion of the "chromosome", before the process that creates sister chromatids, was invalid in the use of the term "chromosome"?

I know that this commented on by a bunch of random people, but the real timeline is as follows: Interphase, Prophase, Metaphase, Anaphase, Telophase, Cytokinesis. — Preceding unsigned comment added by CharlesAustinZimmerman (talkcontribs) 22:47, 16 February 2011


This article's is constantly suffering single-purpose anon-ip unconstructive edits which need to be reverted (occasionally other anon-ips have performed those reverts). Why is mitosis, of all things, the target of such controversy?? Unless, is it highschool teachers trying to interfere with use of the encyclopedia? Anyway, do people think this page is deserving of semi-long-term protections (e.g., restricting editing to logged in users)? Cesiumfrog (talk) 07:46, 5 November 2011 (UTC)Reply[reply]

Good idea, although there are related pages which get the same trouble. I recently managed to get three months semi protection for human skeleton (diff). Johnuniq (talk) 09:14, 5 November 2011 (UTC)Reply[reply]


Hi guys, Karyokinesis redirects here, can someone please just write a quick summary detailing the difference between karyokinesis and cytokinesis, thanks! Kinkreet~♥moshi moshi♥~ 00:05, 24 March 2012 (UTC)Reply[reply]

Karyokinesis is the division of the nucleus, cytokinesis is the division of the cytoplasm. --Khajidha (talk) 14:50, 4 December 2012 (UTC)Reply[reply]

uncoiling of the dna molecule[edit]

Somewhere else on wikipedia there is a diagram showing how a dna molecule is packaged. It is several layers of coils of coils etc. Considering how long this molecule is if it was straightened out I cannot see how it can be unwound without the loose ends getting clogged up in what is left of the fully coiled molecule. I tried this with two bits of string twisted together. As it is untwisted it is essential that the free ends can rotate or else they get twists in themselves. This becomes very obvious as the length of the string increases. It becomes necessary to frequently smooth the twists out of the loose ends. john f (talk) —Preceding undated comment added 10:26, 18 October 2012 (UTC)Reply[reply]

Synchronization of mitosis of several cells?[edit]

In the provided drosophila melanogaster video, the cells go through mitosis in a synchronized manner: All cells seem to almost perfectly go through each mitosis phase identically at the same time. What causes this synchronization? Maybe some form of cell signaling between the cells? --Abdull (talk) 12:35, 13 November 2012 (UTC)Reply[reply]


This article needs semiprotection—There's been loads of vandalism, and I don't think there has been a single constructive edit in the past few days.—Kelvinsong (talk) 01:56, 25 January 2013 (UTC)Reply[reply]

Reference Citation error[edit]

This article has a Cite error in the reference section due to a declared reference no longer being used due to This edit. To remove the error, the reference should be re-instated if still required, or the defined reference hidden/deleted. CV9933 (talk) 13:32, 11 July 2015 (UTC)Reply[reply]


The article illustrates each step of Mitosis devesion clearly. Furthermore, all figurs are helpful. — Preceding unsigned comment added by Halah.F (talkcontribs) 16:38, 20 September 2017 (UTC)Reply[reply]

Uncontrollable mitosis[edit]

Even though this is covered under “mutations” should this not be a separate section? Considering that cancer is a form of uncontrollable mitosis ( ignores cyclin signals, does not go through apoptosis and is “immortal” in the sense that it does not die after many divisions) it is an important section to clarify for the reader, anyone agree?

Editing for Class[edit]

Hello, I am a student from a Cell Biology Class. Throughout the next few weeks, I will be editing this article as there are still some improvements that could be made. I will be putting up my ideas here soon. But, as of ow i will start with grammatical mistakes and statements that may need citations.

At2118 (talk) 00:10, 5 October 2020 (UTC)Reply[reply]


Here is my plan to enhance the article: My plan is to add references as many valid references as possible and add a paragraph to these two sections.


Interphase helps prepare the cell for mitotic division. It dictates whether the mitotic cell division will occur. It carefully stops the cell from proceeding whenever the cell's DNA is damaged or has not completed an important phase. The interphase is very important as it will determine if mitosis completes successfully. It will reduce the amount of damaged cells produced and the production of cancerous cells. A miscalculation by the key Interphase proteins could be crucial as the latter could potentially create cancerous cells [1]. Today, more research is being done to understand specifically how the phases stated above occur.

Errors and other variations

During each step of mitosis, there are normally checkpoints as well that control the normal outcome of mitosis [2]. But, occasionally to almost rarely, mistakes will happen.
