Across
  1. 4. Cells’ surfaces drift like a flexible art display.
  2. 8. A viral case carefully locks its precious cargo.
  3. 10. Enzyme spots for inhibitors to block, off the main path.
  4. 12. Twists and turns create the ultimate DNA ladder.
  5. 13. It’s all about ions—move in, move out, repeat!
  6. 16. It reverses the message back into double form.
  7. 21. Weak connections hold strong relationships here.
  8. 24. An enzyme grabs carbon to kick off photosynthesis.

  15. 35. Scissors with precision that rewrite genetic stories.
  16. 36. This virus prefers its home to be *just right*.
Down
  1. 1. A fat that splits between loving and hating water.
  2. 2. Sulfur links form bonds to strengthen the chain.
  3. 3. Multiple links create chains of sweet energy.
  4. 5. A quick energy transfer straight from the substrate.
  5. 6. Single bases stand tall like ancient triangles.
  6. 7. Two rings make these bases royally pure.
  7. 9. A sneaky block that doesn’t compete for a spot.
  8. 11. The RNA map that leads scissors to their mark.
  9. 14. Shift the code, and chaos ensues.
  10. 15. Heat breaks the protein’s perfect structure.
  11. 17. A 3-carbon middle player in Calvin’s plan.
  12. 18. Three’s company for these fatty energy reserves.
  13. 19. A snug fit comes as the enzyme molds itself.
  14. 20. DNA grows backward but still gets the job done.
  15. 22. DNA strands move oppositely but stay together.
  16. 23. Open channels where water flows without resistance.
  17. 26. Sun’s energy adds a phosphate boost to life.
  18. 29. Dormant but deadly—waiting for the right moment.
  19. 31. A sticky connection that sugars can’t escape.
  20. 32. Life begins with nothing but a spark.
