di centric chromosome

add it to the searching possibilities

"chromosomes with two functional centromeres (dicentric chromosomes"

allthough it is in the text it is not showing up on the search --M siterman 16:09, 28 May 2006 (UTC)[reply]

first usage of "centromere"

Does anybody have an idea who first used the term centromere? I have checked in a book from 1906, the term was apparently unknown to the author. --Dietzel65 14:23, 5 March 2007 (UTC)[reply]

Centromeres involved in the control of puberty??? 144.248.16.30

Strange sentence removed from the article.

The article contains the following:

i think there is an error on this page concerning homologous chromosomes...they do NOT occur in mitosis bu do in meiosis —Preceding unsigned comment added by 75.104.128.38 (talk) 01:25, 4 September 2008 (UTC)[reply]

Acrocentric: If the p (short) arm is so short that is hard to observe, but still present, then the chromosome is acrocentric (The "acro-" in acrocentric refers to the Greek word for "peak."). For example, there are five acrocentric chromosomes in the human genome: 13, 14, 15, 21 and 22. These five chromosomes are the site of genes encoding rRNAs.

I don't understand the meaning of "These five chromosomes are the site of genes encoding rRNAs." - Should this be "The centromeres on these five chromosomes are the site of genes encoding rRNAs." ? Does that imply that the centromeres of other chromosomes are not encoding rRNAs ... What about the Nuclear Organizer (the secondary constriciton)? --Dan|^(talk) 09:29, 6 August 2008 (UTC)[reply]

Size of each centromere

Can anybody tell me what is the exact size of each centromere in humans and mice? Thank you. —Preceding unsigned comment added by 77.124.181.111 (talk) 19:01, 2 October 2010 (UTC)[reply]

I agree; the table only lists the size of the centromeres for the first 3 chromosomes; either there should be an explanation of why only the first 3 are significant or data for the rest should be added (unless we have both missed something) Myoglobin (talk) 16:29, 25 September 2017 (UTC)[reply]

!!! chromosome absence !!! can anybody answer to my Question that what happens if the centromere is absent in the chromosome ??? will the cell division take place ??? what is this condition called ??? — Preceding unsigned comment added by 117.213.193.144 (talk) 13:48, 28 November 2012 (UTC)[reply]

Plurality of kinetochores

A recent edit brought up a good question: during cell division, does each centromere have one or two kinetochores? If there are two (one for each sister chromatid), then the intro should be re-written to make each mention of the kinetochores plural. Myoglobin (talk) 14:38, 2 November 2017 (UTC)[reply]

Broken Reference

Reference 5 links to NIH's Genetics Home Reference and an article on sister chromatid cohesion from 2011, but I can't find such an article anymore. — Preceding unsigned comment added by 71.192.102.252 (talk) 21:39, 13 July 2019 (UTC)[reply]
