What are chromosomes?

Chromosomes are a bundle of DNA and proteins packaged together. They are how your DNA is stored in your cells when it isn’t being “read” by any enzymes. Each chromosome contains a large number of genes. Humans each have forty-six chromosomes, all of which are present in each cell in the body. Chromosomes need to be “unpacked” by enzymes before their DNA can be read by RNA polymerase or other enzymes.
