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






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






3. A widely accepted idea with lots of evidence






4. 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






5. A subset of a population colonizes a new area






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






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






8. Capable of asexual reproduction; most are not






9. 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






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






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






12. Results in a genetically identical inidvidual






13. 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






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






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






16. Related organisms have similar development plans






17. 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






18. Humans selecting certain traits in domestic organisms






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






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






21. Directional selection - Disruptive selection - Stabalizing






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






23. Selects for the middle and against the extremes






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

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






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






27. Cells that can turn into other cells






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






29. Form of reproduction more used because it creates Variation






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






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






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






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






34. 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






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






36. 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






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






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






39. The idea that characteristics can enhance an organisms survival






40. Selects for the extremes and against the middle






41. One extreme is selected over the other






42. 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






43. Direct competition for mates with the same sex






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






45. Sometimes different species share common ancestors






46. Change in alleles due to random chance






47. The organism with the most advantageous traits will survive






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






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






50. The change in a populations genetics
