Across
  1. 2. we all need a certain amount of this
  2. 4. fixes the double helix and adds nucleotides
  3. 7. Discovered equal amounts of thynine and adenine and cytosine and guanine
  4. 8. bonds with phosphates
  5. 11. strand stays the same during dna replication
  6. 13. bonds with thynine
  7. 14. bonds with adenine
  8. 16. unzips the double helix
  9. 17. replication whens 2 strands unzip to form a new strand
  10. 18. we get this from our parents
Down
  1. 1. bonds to guanine
  2. 3. Built a 3D model of DNA
  3. 5. this bond is located in the double helix
  4. 6. Our body is composed of this
  5. 9. conservative what a double helix is called
  6. 10. This bond has sugars and phosphates
  7. 12. helix what a new strand and old strand form
  8. 15. this is an organic molecule
