What do chromosomes do?

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.

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)
