  4. 11. long arm of eukaryotic chromosomes.
  5. 12. a protein that gives structural support for chromosome + DNA wraps around this in a chromosome
  6. 15. DNA that is not tightly wound up and more “open” this section of DNA is considered to be turned ON
  7. 16. Are pairs of chromosomes with the same gene regions
Down
  1. 1. Attached together by a centromere - they separate from each other during cell division
  2. 2. An individual’s complete set of chromosomes
