Way back in the dark ages when I went to high school, we where taught that humans had 32(?) chromosomes and that each chromosome contained individual genes which was what actually passed on characteristics and traits like eye color etc. So now there is DNA and the humane genome is billions of bits, links, whatever long.
So how does DNA relate to chromosomes and genes? I understand that genes are actually segments of the DNA molecule; but, what is the relationship if any between chromosomes and DNA molecules? Does each chromosome contain one complete molecule of DNA or are chromosomes completely out of the picture now? (Yet they still talk about X and Y chromosomes and genes carried on or within or attached to them.)
