Across
  1. 4. A single base change — small typo, potentially big consequences
  2. 7. Genetic material wrapped in protein — not quite alive
  3. 12. DNA → RNA → Protein — the sacred flow of genetic info
  4. 15. Adds a chemical tag to DNA — usually silences gene expression
  5. 16. Copying DNA before cell division
  6. 17. Enzyme that lays down an RNA primer to get replication started
  7. 19. DNA strand built continuously — smooth sailing
  8. 22. Heritable changes in gene activity without altering the DNA sequence
  9. 23. Enzyme that unzips DNA strands
  10. 25. Carries the genetic message from nucleus to ribosome
  11. 26. Noncoding regions cut out during RNA processing
  12. 27. Strand built in Okazaki fragments — like trying to read backwards
Down
  1. 1. Enzyme that builds the new DNA strand — always reads 3’ to 5’, builds 5’ to 3’
  2. 2. Viral replication cycle that ends with cell bursting
  3. 3. Making proteins from RNA — the cell’s version of decoding a recipe
  4. 5. Making RNA from DNA — like copying notes from the master file
  5. 6. Editing RNA before it leaves the nucleus — cut, cap, and tail
  6. 8. DNA base that pairs with thymine — unless it’s RNA, then it pairs with uracil
  7. 9. Caused by insertions or deletions — messes up the entire reading frame
  8. 10. A pairs with T, C pairs with G — nature’s strict dating rules
  9. 11. Proteins DNA wraps around — like spools for your genetic yarn
  10. 13. Brings amino acids during translation
  11. 14. A group of prokaryotic genes regulated together — one switch for multiple lights
  12. 18. Coding sequences that stay in the final mRNA — the usable footage
  13. 19. Viral cycle where DNA inserts into host genome and chills
  14. 20. Enzyme that seals DNA fragments — like genetic glue
  15. 21. Any change in DNA — can be harmless, helpful, or a total disaster
  16. 24. Short fragments of DNA on the lagging strand
