Across
  1. 5. both alles look different
  2. 6. flow of genetic info within a biological system
  3. 9. each new DNA molecule consist of one original
  4. 16. containing organelles found in the cell or green plants and some prustist
  5. 19. are specific sequences of DNA that code for proteins
  6. 20. both alles look the same
  7. 24. chemical reactions that do not require the presence of oxygen
  8. 25. chemical reactions that require the presence of oxygen
  9. 26. what is does
  10. 28. structures within the cell nucleus that contain dna
  11. 29. what it looks like
  12. 30. what is made of produced
Down
  1. 1. the character change-disrupts function
  2. 2. are weak attractions between the nitrogenous bases of the dna strands
  3. 3. organisms that use energy from the sun or energy stored in chemical compounds to manufacture their own nutrients
  4. 4. eukrytotic membrane -band organelles that transform energy stored in food molecules
  5. 7. too many species for resources available
  6. 8. moleecule similar to DNA but usually single stranded
  7. 10. small particles important for living things
  8. 11. what you start with
  9. 12. is the process by which DNA makes a copy of itself
  10. 13. multiple monomers connected together
  11. 14. new species evolves
  12. 15. maintaining stable conditions
  13. 17. to live
  14. 18. number of times /average /how often
  15. 21. is a molecule that carries the genetic blueprint of living organisms
  16. 22. speed up chemical reactions
  17. 23. rate how fast/slow organisms have babies
  18. 27. light absorbing pigment in pants and some prusit that require photosynthesis
