Across
  1. 2. the tips of chromosomes
  2. 4. pairs with thymine
  3. 6. type of bond that holds a nucleotide together
  4. 9. the process of copying DNA
  5. 11. type of bond that connects on nitrogenous base to another
  6. 12. part of the scientist team that worked with bacteriophages and had the public "follow the light"
  7. 13. worked with pneumonia and mice to determine if there was a way to manipulate organisms by transforming chemical factors
  8. 14. tested the 4 macromolecules to identify nucleic acids as the transforming material
  9. 15. the shape prokaryotes use to store their genetic information
  10. 16. pairs with cytosine
  11. 17. monomer of a nucleic acid
  12. 19. percent of adenine in a sample that has 40% guanine
  13. 21. the enzyme that "unzips" DNA
Down
  1. 1. term used to describe the shape of DNA
  2. 3. Franklin's lab partner who stole Photograph 51
  3. 5. part of the scientist team that won the Nobel Prize for the discovery of the chemical shape of DNA
  4. 7. took an X-ray photo of DNA that revealed the twisted, helical structure
  5. 8. part of the scientist team that helped determine DNA, not proteins, was the genetic material
  6. 10. type of sugar in a DNA nucleotide
  7. 18. noticed that certain nitrogenous bases almost always appear in certain pairs
  8. 20. part of the scientist team that used Franklin's picture to determine the final 3D shape of a DNA molecule
