– This is a common misconception, mitosis consists of only 4 stages, Prophase, Metaphase, Anaphase and Telophase (PMAT), Interphase and Cytokinesis are not considered part of the process of mitosis as they are not involved in the actual division of the cell nucleus. Interphase is responsible for preparing a cell to ENTER mitosis and Cytokinesis is responsible for the complete division of a cell's cytoplasm. ] (]) 03:15, 13 August 2019 (UTC) SwoodyJr | |||

Nerve cells
Currently the page lists nerve cells as cells which enter interphase for extended periods of time:
Some cells, such as nerve cells, can stay in interphase for decades.
Are nerve cells really in interphase here or are they in G0? I would think that, metabolically speaking, nerve cells are in G0. Cells in interphase grow and get ready to divide.
once again why isn't this part of cell cycle...there are so many articles about the cell cycle why can't we just put them into one? Nominaladversary 01:56, 31 March 2006 (UTC)
Wrong phase?
'In prophase the two chromatids are still connected by something called ened in telephase.
interphase
There should be a better description of G1, S, and G2.
G1- major growth occurs along with metobolic activity
S- DNA synthesis and duplication of chromosomes
G2- mitochondria and other organelles are manufactured while the cell is prepared for mitosis

Listing inconsistent Cell Cycle phases and "First"
If the text "Interphase is the first part of the Cell Cycle. The Cell Cycle includes three stages: Interphase, Mitosis, and Cytokinesis." is to be included in Interphase then there are a few questions:
Where is the citation?
Why put cell cycle information in Interphase when there is a complete description in Cell Cycle?
Why add the description " ...includes three stages: Interphase, Mitosis, and Cytokinesis.." when this is inconsistent with the description in Cell Cycle and {{Cell Cycle}} that appears, amongst other places, at the bottom of Interphase?
How can a cycle that has occurred for hundreds of millions of years have a step that can be meaningfully called the "first part"?

- I've added, to the interphase article three sentences which, I believe, meet you concerns and are consistent with related articles. And rather than using the term cytokinesis, I used metaphase which is consistent with the related articles.
Does this meet with your agreement? If you concur; I will add the appropriate citations.

Assessment comment
The comment(s) below were originally left at Talk:Interphase/Comments, and are posted here for posterity. Following several discussions in past years, these subpages are now deprecated. The comments may be irrelevant or outdated; if so, please feel free to remove this section.
Importance: This should be at least Mid-Importance, if not High-Importance, because it is briefly taught on high school level. Changed rating to "high" as this is high school/SAT biology content, part of the cell cycle. - tameeria 21:17, 18 February 2007 (UTC) |
