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. Direct competition for mates with the same sex






2. Directional selection - Disruptive selection - Stabalizing






3. Humans selecting certain traits in domestic organisms






4. A widely accepted idea with lots of evidence






5. Selects for the middle and against the extremes






6. Way more offspring are produced than by sexual reproduction






7. Sometimes different species share common ancestors






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






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






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






11. All species on earth are fixed; no changes - no new species - no extinction






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






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






14. Believed that change was gradual;Gradualism(the mechanisms of the world - then - are the same today)






15. A subset of a population colonizes a new area






16. Traits that are neither advantageous nor disadvantageous; there is no selection






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






18. The change in a populations genetics






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






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

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






22. Differences in appearances between the sexes






23. The idea that characteristics can enhance an organisms survival






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






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






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






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






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






29. Results in a genetically identical inidvidual






30. Capable of asexual reproduction; most are not






31. Selects for the extremes and against the middle






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






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






34. 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






35. Choosing the sperm/egg/embryo that will produce the desired child depending on DNA(genes)






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






37. The process of sperm sorting; separating the male sperm from the female sperm; difference told by swimming speed; boy sperm swim faster than girl sperm; Theory might have flaws in it though - only works 50% of the time






38. 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






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






40. The organism with the most advantageous traits will survive






41. Form of reproduction more used because it creates Variation






42. 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






43. Taking good genes to replace bad genes; almost never works; has unintended side effects; sometimes just doesn't work; protein becomes degraded - etc






44. Sexual partners chosen based on some characteristics






45. 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






46. When a population becomes smaller and a few individuals survive the event






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






48. 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






49. An accumulation of genetic charges over a certain amount of time






50. In related organisms the underlying anatomy is similar even when the function is different
