  2. The shape of the DNA molecule resembles a twisted ladder and is described by this name. What is a double helix? 5

  3. These are the correct base pairs found on the DNA molecule. What is adenine and thymine: and cytosine and guanine? 10

  4. Each repeating nucleotide of DNA contains these three elements. What is a sugar, a phosphate group and a nitrogen base? 15

  5. A strand of DNA formed by the splicing of DNA from two different species is known as this. What is recombinant DNA? 20

  6. The two strands of the double helix are held together by these bonds. What are hydrogen bonds? 25

  7. This group of Pacific Islands proved to be very influential to Darwin’s theories. What are the Galapagos Islands? 5

  8. The process by which organisms with traits best suited to their environment are more likely to survive and reproduce is known as this. What is Natural Selection? 10

  9. The human appendix is an example of this. What is a vestigial structure? 15

  10. The relationship between a honey bee and a dandelion is an example of this type of evolution. What is coevolution? 20

  11. The human arm, a dolphin’s flipper and a bird’s wing are examples of this. What are homologous structures? 25

  12. This is the science of classifying living things. What is taxonomy? 5

  13. This man developed the system of binomial nomenclature. Who is Carolus Linnaeus? 10

  14. This language is most commonly used in the classification of living things. What is Latin? 15

  15. This is the correct order of biological hierarchy from largest to smallest. What is Domain, kingdom, phylum, class, order, family, genus and species? 20

  16. The scientific name of a organism consists of these two parts. What are the genus and species? 25

  17. Bacteria are the only examples of this type of cell: without a nucleus. What are prokaryotic cells? 5

  18. These are tail-like structures used by some bacteria for movement. What are flagella? 10

  19. A typical bacteria cell has this many chromosomes. What is one? 15

  20. This is the name given to any disease-causing agent. What is a pathogen? 20

  21. Gram positive bacteria will stain this color. What is purple? 25

  22. A virus consists of a piece of nucleic acid surrounded by this. What is a protein coat? 5

  23. Viruses that infect bacteria cells are known as this. What are bacteriophages? 10

  24. HIV is a virus that shuts down this body system. What is the immune system? 15

  25. Retroviruses use this enzyme to cause their host cells to transcribe DNA from an RNA template. What is reverse transcriptase? 20

  26. This is the viral cycle in which viral dna “hides” in the host cell’s dna before becoming active. What is lysogenic? 25
