euchromatin and heterochromatin definitions

The current text on euchromatin and heterochromatin being equivalent to the beads on a string and 30nm fiber are wrong. The beads on a string seems to be very rare in physiological conditions and the 30nm fiber is present in both euchromatin and heterochromatin. The difference between euchromatin and (the different kinds of) heterochromatin lies in the higher order compactness. (Lodish, molecular cell biology) Kuije002 (talk) 11:52, 3 May 2012 (UTC)

Old image

Created a new and more appropriate image showing major chromatin structures. This is the old figure.

New Image

The new image is beautiful but the simple double structure helix is left handed, where the actual structure in cells is a right handed helix. It need to be fixed.

What is polytene chromatin? My teacher asked us to define this for Genetics homework but I have been unable to find any answers and wikipedia. —Preceding unsigned comment added by Acarrell (talk • contribs) 22:13, 13 September 2007 (UTC)

Vandalism

This page seems to be getting vandalised a lot, or am I just being an anti-vandal n00b? - Zephyris _Talk 23:18, 12 December 2006 (UTC)

Role of chromatin in transcription

I think this article needs to include a section emphasizing the role chromatin plays in transcription, or at least a link to a relevant section on the transcription page (which currently needs a lot of work)...MDG38 16:12, 8 November 2007 (UTC)

External links modified

Hello fellow Wikipedians,

I have just added archive links to one external link on Chromatin. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

Added archive {newarchive} to http://www.chromatin.co.uk/

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

30nm Structure - non existant ?

Hi, I was recently teaching mitosis, so looked up on condensation of chromatin. While I was browsing sources I found that some 2012 reviews / articles point towards no 30 nm structure existing - at least in mammals (fractal folding of 10 nm structure was the proposed solution). I'm wondering a) whether that is still the currently held view, and b) whether the info in this article needs updating, regardless of which model exactly is currently assumed to be most likely / best supported by the evidence.

You're right, I don't know why that's stayed on the article for so long. I've deleted the content pertaining to the incorrect 30nm model, but the article still needs to be updated with current accurate models. Here's the first two results from google:
