What do chromosomes actually do???

Basically, they’re clumps of genetic material. Each chromosome contains a certain number of genes. Genes are stretches of DNA which contain the instructions for certain proteins. RNA polymerase will bind to a gene, produce mRNA, and begin the process for making that protein. We classify and draw chromosomes based on their extremely condensed state when a cell is dividing because it’s easiest to see them that way (Otherwise we’d be studying squiggles which is much less satisfying to draw)
