What is a chromsome and what does it do?
Question Date: 2008-04-11
Answer 1:

The chromosomes are packages of DNA. As humans, we have 23 pairs. So you got one chromosome #1 from your mom and one from your dad. When a cell divides, first each chromosome makes a copy of itself, then the copy goes into one of the new cells, and the original goes into the other. That means that the two new cells have the same information as the original cell.
