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. 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






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

3. Related organisms have similar development plans






4. 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






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






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






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






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






9. Humans selecting certain traits in domestic organisms






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






11. Directional selection - Disruptive selection - Stabalizing






12. 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






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






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






15. Selects for the extremes and against the middle






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






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






18. 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






19. 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






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






21. Form of reproduction more used because it creates Variation






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






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






24. Change in alleles due to random chance






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






26. 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






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






28. Sometimes different species share common ancestors






29. Capable of asexual reproduction; most are not






30. Mate choice; one sex chooses their mate






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






32. The idea that characteristics can enhance an organisms survival






33. Cells that can turn into other cells






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






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






36. Results in a genetically identical inidvidual






37. 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






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






39. Sexual partners chosen based on some characteristics






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






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






42. One extreme is selected over the other






43. The screening of embryos for genetic disorders; done in In Vitro fertilization(fertilization in a petri dish); PGD removes one cell from the embryo and screens it genetically; embryos with disorders are discarded - ones without are kept and implanted






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






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






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






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






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






49. The organism with the most advantageous traits will survive






50. The change in a populations genetics
