Test your basic knowledge |

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






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

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






4. A widely accepted idea with lots of evidence






5. Selects for the middle and against the extremes






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






7. Selects for the extremes and against the middle






8. Humans selecting certain traits in domestic organisms






9. Way more offspring are produced than by sexual reproduction






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






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






12. Sometimes different species share common ancestors






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






14. 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






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






16. Cells that can become only a few different types of cells; mostly adult stem cells; found in bone marrow - the skin epidermis - etc; can sometimes be turned into Totipotent stem cells






17. Change in alleles due to random chance






18. 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






19. Sexual partners chosen based on some characteristics






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






21. Form of reproduction more used because it creates Variation






22. Differences in appearances between the sexes






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






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






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






26. Directional selection - Disruptive selection - Stabalizing






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






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






29. One extreme is selected over the other






30. 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






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






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






33. The change in a populations genetics






34. The idea that characteristics can enhance an organisms survival






35. Results in a genetically identical inidvidual






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






37. 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






38. 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






39. Cells that can turn into other cells






40. 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






41. Direct competition for mates with the same sex






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






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






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






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






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






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






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






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






50. A subset of a population colonizes a new area
