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. Related organisms have similar development plans






2. Direct competition for mates with the same sex






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

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






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






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






7. 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






8. A subset of a population colonizes a new area






9. 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






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






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






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






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






14. Mate choice; one sex chooses their mate






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






16. The change in a populations genetics






17. Cells that can turn into other cells






18. The idea that characteristics can enhance an organisms survival






19. Results in a genetically identical inidvidual






20. Change in alleles due to random chance






21. The organism with the most advantageous traits will survive






22. Differences in appearances between the sexes






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






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






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






26. 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






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






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






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






30. Selects for the extremes and against the middle






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






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






33. One extreme is selected over the other






34. Sexual partners chosen based on some characteristics






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






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






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. 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






39. Directional selection - Disruptive selection - Stabalizing






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






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






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






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






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






45. A widely accepted idea with lots of evidence






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






48. Sometimes different species share common ancestors






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






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