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. Differences in appearances between the sexes






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






3. 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






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






5. Results in a genetically identical inidvidual






6. Capable of asexual reproduction; most are not






7. A widely accepted idea with lots of evidence






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






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






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


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






12. 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






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






14. 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






15. Selects for the middle and against the extremes






16. Related organisms have similar development plans






17. Mate choice; one sex chooses their mate






18. Sometimes different species share common ancestors






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






20. Change in alleles due to random chance






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






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






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






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






25. Sexual partners chosen based on some characteristics






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






27. The idea that characteristics can enhance an organisms survival






28. The change in a populations genetics






29. 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






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






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






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






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






34. A subset of a population colonizes a new area






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






36. Form of reproduction more used because it creates Variation






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






38. One extreme is selected over the other






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






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






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






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






43. Direct competition for mates with the same sex






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






45. The organism with the most advantageous traits will survive






46. 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






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






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






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