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. Mate choice; one sex chooses their mate






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






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






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






5. 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






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






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






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






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






10. Differences in appearances between the sexes






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






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






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






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






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






16. Way more offspring are produced than by sexual reproduction






17. Capable of asexual reproduction; most are not






18. Direct competition for mates with the same sex






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






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

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






22. 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






23. Change in the DNA sequence of an individual; the only true way to get a new allele; the source of all heritable variation






24. Selects for the middle and against the extremes






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






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






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






28. Selects for the extremes and against the middle






29. Related organisms have similar development plans






30. Directional selection - Disruptive selection - Stabalizing






31. A widely accepted idea with lots of evidence






32. Form of reproduction more used because it creates Variation






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






34. 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






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






36. One extreme is selected over the other






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. Results in a genetically identical inidvidual






39. 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






40. The organism with the most advantageous traits will survive






41. 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






42. 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






43. The change in a populations genetics






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






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






46. Sometimes different species share common ancestors






47. Change in alleles due to random chance






48. The idea that characteristics can enhance an organisms survival






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






50. Cells that can turn into other cells
