CSET Genetics And Evolution

Subjects : cset, science, genetics
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Ribosomal RNA; type of RNA that makes up part of the ribosome






2. Evolution resulting from small specific genetic changes that can lead to a new subspecies






3. The offspring of a cross between two inbred lines within a single species. May also refer to the offspring of across between two species






4. Mating of an individual of unknown genotype but dominant phenotype w/ a homozygous recessive individual






5. Which structure contains anticodons






6. Proteins are made of...






7. Structure present in an organism however does NOT have a known function. May link organisms with similar vestigial structures. Example: appendix - coccyx bone - whale leg bones.






8. One of the types of fossils made from hardened tree resin. Preserves both hard and soft parts.






9. Messenger RNA; type of RNA that carries instructions from DNA in the nucleus to the ribosome






10. Identical alleles for a gene






11. It means chromosomes are paired. One of each chromosome in a pair originates from the father and one from the mother. They affect the same trait - but don't necessarily cause the same expression of the trait.






12. Dna moves during electrophoresis because of...






13. Term used to refer to an organism that has two different alleles for the same trait. e.g Tt is the heterozygous genotype for Tall.






14. A population partially isolated from other populations of the same species






15. A limb with five digits (fingers)






16. A process that results in an allele having a different probability of remaining in the gene pool compared with that of another allele






17. The comparison of the structures of different organisms






18. Heteros have a phenotype tintertmediate b/t phenotypes of the 2 homoz






19. Organism is preserved at very low temperatures. Preservation of both hard and soft parts can occur.






20. Visual expression of a trait






21. Are noncoding sequences in the gene that are removed from RNA after transcription






22. Building block of a protein






23. Molecules that join together to form DNA and RNA. Monomers that make up a nucleic acid






24. Periods of rapid evolution punctuated by periods of little change






25. Is a base found in DNA and RNA. In DNA its partner is Thymine. In RNA its partner is Uracil






26. DNA is made of...






27. A taxon originating from and including a single common ancestor






28. Ribosomes are made of...






29. DNA that is coiled around proteins






30. Condition in which an organism has extra sets of chromosomes






31. Describes the isolation of a physical barrier e.g. body of water (ocean) or mountains






32. The capacity of an individual of certain genotype to reproduce. It is usually equal to the proportion of the individual's genes in all the genes of the next generation






33. Process by which individuals that are better suited to their environment survive and reproduce most successfully; also called survival of the fittest






34. Building block of a nucleic acid (DNA and RNA)






35. Is a base found in DNA and RNA. This base pairs with Cytosine in DNA






36. The enzyme that binds to the promoter region of a gene during transcription is called...






37. Populations that can interbreed with neighboring populations but not with populations separated by larger geographical distances






38. Physical characteristics of an organism based on its genotype. e.g. Plant that has a genotype of TT will have a phenotype of Tall.






39. Nucleotides that control which amino acids are added during protein synthesis






40. Era of recent life that began about 66 million years ago and continues today; includes the first appearance Hominids






41. Innate trait; shared ancestry






42. A geographic gradient in the extent to which a character is developed in a species






43. A distinct population of a species that varies from other populations of the same species.






44. It is the time from when the Earth formed and simple life - forms evolved (and it is the longest era)






45. Selection for the ability to obtain a mate






46. Human - like species that existed millions of years ago as witnessed through fossil evidence.






47. Structures in different but related species that are derived from the same ancestral structure but now serve different purposes.






48. Trait evolves overtime; NO common ancestry






49. Another term for pure breeding






50. Disappearance of a species from all parts of its geographical range
