Across
- 1. A plant’s growth promoter, encouraging cells to divide and differentiate.
- 2. A virus that feasts on bacteria, injecting its genetic payload.
- 5. Airy helpers, these cells line alveoli for gas exchange.
- 7. Nerve signals leap between nodes, speeding transmission.
- 8. Extra sets of chromosomes give some plants an evolutionary edge.
- 9. Enzymes with a cutting edge, slicing DNA or RNA as needed.
- 13. A protective shell around eggs, crucial to fertilisation.
- 14. A repeating unit of four, once thought to structure our genes.
- 16. Short DNA pieces fill in the lagging strand during replication.
- 18. Pyruvate meets CoA, linking glycolysis to the citric acid cycle.
- 19. A viral invasion ends in destruction—cells burst, releasing new foes.
- 23. Sulphur bonds stabilise proteins, linking chains together.
- 24. Genetic reshuffling creates offspring with new combinations.
- 26. Bacteria chat chemically, coordinating behaviour in groups.
- 27. Twisting like a spring, this protein structure forms in the fold.
- 28. A double-ringed base, found in both DNA and RNA sequences.
- 30. Channels linking plant cells, bridging gaps with cytoplasmic threads.
- 31. A branching method of sorting species by shared ancestors.
- 33. A molecular middleman passing signals between membranes and the inside.
Down
- 1. Proton gradients power ATP synthesis, driving cellular energy.
- 3. Carbon is lost as CO2, step by step in metabolic pathways.
- 4. A regulatory protein that keeps the cell cycle ticking.
- 6. A molecule always ready to restart the Krebs cycle.
- 10. The smallest contractile unit of muscle, where filaments slide.
- 11. Protein partners move substances in tandem across membranes.
- 12. A rightward move, where pH changes help unload oxygen.
- 15. Not too hot, not too cold—just right for life to thrive.
- 17. The ancestor of all, a shadow of life’s ancient beginnings.
- 20. Cells separate spaces for tasks, keeping chaos contained.
- 21. A carbon-capturing enzyme, central to a plant's dark work.
- 22. A hormone driving cycles and development in the reproductive system.
- 25. Identical twins, often the focus of studies on nature versus nurture.
- 29. Genetic scissors guided by RNA, snipping DNA with precision.
- 32. A giant in proteins, anchoring muscle elasticity with strength.
