Across
  1. 7. The DNA run parallel to one another in opposite directions
  2. 8. Proteins that stop separated strands from joining back together
  3. 10. The enzyme that acts as the glue
  4. 11. The sugar found in DNA
  5. 12. This enzyme cuts out the RNA primers
  6. 16. This type of bond forms between complementary base pairs
  7. 17. To begin replicating the DNA, it requires a starting point. This is created by an enzyme called...
  8. 18. Composed of a sugar, phosphate, and base
  9. 19. The name of the fragments produced by the lagging strand
  10. 20. The number of bonds between adenine and thymine
  11. 22. Two ring structure (adenine, guanine)
Down
  1. 1. Unwinding the DNA puts it under a lot of tension and this enzyme helps to relieve this by relaxing the DNA from its super-coiled structure
  2. 2. The base that pairs with adenine
  3. 3. This enzyme associates with the DNA and builds the new strands by adding DNA nucleotides one at a time
  4. 4. The base that pairs with cytosine
  5. 5. Single ring structure (thymine, cytosine)
  6. 6. The bond between one nucleotide and the next
  7. 9. The Y-shaped structure where replication begins
  8. 10. The strand of DNA that is synthesized continuously in the 5' to 3' direction
  9. 13. The strand of DNA that requires new primers and can only be synthesized in small chunks
  10. 14. This enzyme unzips the double-stranded DNA molecule, separating it into two single strands
  11. 15. This scientist discovered that the amount of adenine equals the amount of thymine and the amount of guanine equals the amount of cytosine
  12. 21. The number of bonds between cytosine and guanine
