  1. 4. A characteristic or feature you can observe in an organism, like eye color, height, or hair texture
  2. 5. The process of passing genetic traits from parents to their offspring
  3. 7. mutation A genetic change that makes it harder for an organism to survive and reproduce
  4. 8. What something does; its job or purpose in the body
  5. 10. Molecular machines that do most of the work in your body, like building structures, fighting diseases, and carrying messages between cells

  1. 1. mutation A genetic change that helps an organism survive and reproduce better in its environment
  2. 2. How something is built or put together; the shape, size, and arrangement of parts
  3. 3. affects the visiable trait (phenotype)
  4. 6. Thread-like structures in your cell's nucleus that store genetic information; think of them as filing cabinets that organize your genes
  5. 9. A specific section of DNA that acts like a recipe or instruction manual telling your body how to make a particular protein
  6. 11. mutation A genetic change that doesn't significantly help or hurt an organism's survival
  7. 12. Any living thing, from bacteria to plants to animals
  8. 14. A change that occurs in a gene over time; like changing words in a recipe
  9. 17. The basic building block of all living things; contains genetic material and proteins
  10. 18. The molecule that contains all the genetic instructions for living things; like a master cookbook for your body
  11. 20. Different versions of the same gene; you get one from your mom and one from your dad
