Recombinant Dna Technology

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. Related organisms have similar development plans






2. Cuts DNA in specific sites; the fragments created are usually predictable






3. Directional selection - Disruptive selection - Stabalizing






4. Differences in appearances between the sexes






5. First to publish mechanisms for evolution; Had 2 idea: Use and disuse - use it more gets bigger; less it disappears - Inheritance of acquired characteristics - pass on changes to offspring






6. A circular piece of DNA in bacteria where the gene is placed in Recom. DNA technology






7. Cells that can turn into other cells






8. Sometimes different species share common ancestors






9. A widely accepted idea with lots of evidence






10. Recessive traits persistent to a certain population; recessive alleles hide from selection






11. Another method designed to sort female sperm form male sperm; goes by size of sperm; females are bigger than male sperm






12. Set sail on the HMS Beagle to travel the islands and areas for signs of evolution; First book written in 1839 'voyage of the Beagle'; Second book published in 1859 'The Origin of Species by means of Natural Selection






13. One extreme is selected over the other






14. The change in a populations genetics






15. Mate choice; one sex chooses their mate






16. Change in alleles due to random chance






17. Can make large quantities of product; infection free; less expensive than a natural source






18. The movement of genes between two populations e.g. migration - immigration






19. The more common a trait becomes the more likely it will be selected against






20. A process to help separate DNA fragments using an electrical current; helps to compare DNA samples by fragment pattern






21. Came up with the term Uniformitarianism(mechanisms for change in the past still occur today; believed at first there was no evolution






22. Mutation - Natural selection - Genetic drift - Bottleneck effect - Founder effect - Gene flow - and Mate choice/non - random mating






23. Forms that show how an organisms anatomy change over time






24. Invented the binomial method(naming of species); also believed that life was fixed






25. Capable of asexual reproduction; most are not






26. Selects for the middle and against the extremes






27. Came up with the term catastrophism(sudden events that lead to extinction - but not in todays time)






28. Way more offspring are produced than by sexual reproduction






29. Heterozygous chromosomes have an affect on an individuals genetics/alleles






30. Number of offspring in the next generation; your contribution to the gene pool






31. The screening of embryos for genetic disorders; done in In Vitro fertilization(fertilization in a petri dish); PGD removes one cell from the embryo and screens it genetically; embryos with disorders are discarded - ones without are kept and implanted






32. Closely related organisms have more similar DNA sequences and protein structures






33. 1.edits existing variation by using the material it has(variation that exists in population/ no new traits created by natural selection) 2. Has historical constraints(change in old structures) 3. Adaptations are compromises (good for one thing - bad






34. Pharmaceutical animals; cloned animals used ot produce products for humans


35. Comparing an unknown sample of DNA to a known sample by using Gel Electrophoresis; used in crime scenes - paternity tests - and remains identification






36. The organism with the most advantageous traits will survive






37. Selection fro or against environment; leads to evolution only if variation has genetic components






38. Distribution of organisms related to evolution; different organisms play the same roles on different continents; island organisms resemble organisms on nearby mainland






39. The idea that characteristics can enhance an organisms survival






40. Scientific explanation of how life changes over time - science is based off of evidence - science is obtained with observation and testing - science is always open to question






41. Takes the gene from a needed product - puts it into another organism (usually bacteria) and it will make duplicates of the product






42. A group of interbreeding organisms living in the same place at the same time






43. Results in a tissue or an organ that is identical to the DNA donor






44. Humans selecting certain traits in domestic organisms






45. Theory of a stable - nonevolving population in which frequency of alleles do not change; only occurs in large - isolated populations with random mating - and no natural selection or mutations






46. Subset of natural selection that increases the likelihood of mating specifically






47. A subset of a population colonizes a new area






48. Selects for the extremes and against the middle






49. Cells that can become any cell in the body; found in the embryo






50. Results in a genetically identical inidvidual
