md97 Posted October 30, 2012 Posted October 30, 2012 What do chromosomes do? I got down that it stores genetic information, but I need more for my project. Hopefully this is the right topic in the eyes of zombique. Quote
SidtheSnail Posted October 30, 2012 Posted October 30, 2012 You spelled her name wrong. It's Zombiiesque. 2 I`s http://lmgtfy.com/?q=Chromosomes Lydia Trebond, lindorie, Mouseykins and 6 others 9 Quote
pchau123 Posted October 30, 2012 Posted October 30, 2012 They duplicate in interphase I of meiosis I and then they pair up as sister chromosomes in prophase until metaphase I where they line up in the middle and then it's where the sister chromosomes (tetrad) separate into two different cells starting in anaphase and cytokinesis. After that in Meiosis II they line up again and this time sister chromosomes come apart and turns into sister chromatids. Learned meiosis in Gen Bio I in college and I remembered it and felt the need to recite it :3... They do a lot though. You're going to have to be more specific. Quote
The Bandit Posted October 30, 2012 Posted October 30, 2012 rofl, I love lmgtfy - never seen that before. I was going to suggest http://en.wikipedia.org/wiki/Chromosome md97 1 Quote
passiflora Posted October 30, 2012 Posted October 30, 2012 What's the project? They don't really do much other than store genetic information (as you said). They're literally just pieces of DNA. Other things that might be related/of interest: - they divide so that new cells have a copy of the genome (mitosis/meiosis) - looks different depending on what the cell is doing (chromatin - uncondensed vs condensed) - they take on different forms in prokaryotes and eukaryotes (e.g. bacteria vs humans) - chromosome abnormalities - extra copies, deletions, etc. (e.g. Down Syndrome) Quote
Angeló Posted October 30, 2012 Posted October 30, 2012 you just threw me 12 years back !! anyway chromosomes carry genes which are our whole genetic map ... I'm no good at explaining stuff this is why I could never be a professor lol Quote
Emily Posted October 30, 2012 Posted October 30, 2012 http://en.wikipedia.org/wiki/Chromosome Wikipedia for the win. Google is also an option. Mouseykins 1 Quote
khaos Posted October 30, 2012 Posted October 30, 2012 the do some stuff with mitosis and make spindle fibers for mitosis and meiosis thats pretty much all i know like everyone said, google+wikipedia. Quote
sideways Posted November 1, 2012 Posted November 1, 2012 I heard wihtout enough of them you get the downes Quote
