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