Across 4. Copies instructions for protein synthesis from DNA 5. The ability to make copies itself 8. helpful traits become common but harmful traits become rare 11. Bacteria develop resistance to antibiotics 14. Complex Molecule, Double Helix Backbone 16. Frequency of genetic changes appearing 17. tRNA gathers amino acids and transports them to ribosome where rRNA catalyzes protein synthesis on the mRNA 20. Thought Life arose in water 23. Order, Growth and Development, Energy Utilization, Response to environment, Reproduction, Evolutionary adaption 26. Entire set of genes 28. Can be caused by UV Light, Cosmic rays, Radioactive elements, DNA replication 29. The ability to grow;add mass and/or capabilities

Down 1. Overarching structure and/or organization to the component molecules and atoms 2. Adenine, Guanine, Thymine, Cytosine 3. A---->T (only), G----->C (only) 6. Ability to sense and react to environment 7. Helix splits into two, each strand gets new partner 9. Living organisms change, or evolve, over successive generations as they respond and adapt to the environment and other organisms 10. Decoding Process 12. Three domains Bacteria, Archaea and Eucarya 13. Can harvest energy and use it to grow, react, develop, and counteract the tendency toward decay 15. 4^3=64, Codon 18. Catalyzes protein Synthesis 19. Transports amino acids to the synthesis site 21. Chains of amino acids 22. Self sustaining chemical system capable of evolution 24. Thought Evolution is the idea of passing traits acquired during lifetime to oppspring 25. Each set of instructions 27. Single stranded polymer with a different backbone and Uracil instead of Thymine
