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






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






3. 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






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






5. 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






6. Direct competition for mates with the same sex






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






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






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






10. Directional selection - Disruptive selection - Stabalizing






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






12. One extreme is selected over the other






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






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






15. 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






16. 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






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






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






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






20. Cells that can turn into other cells






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






22. Selects for the extremes and against the middle






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






24. Form of reproduction more used because it creates Variation






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






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






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






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

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






30. Change in alleles due to random chance






31. Sexual partners chosen based on some characteristics






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






33. Related organisms have similar development plans






34. Way more offspring are produced than by sexual reproduction






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






36. Mate choice; one sex chooses their mate






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






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






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






40. 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






41. 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






42. 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






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






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






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






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






47. A subset of a population colonizes a new area






48. Sometimes different species share common ancestors






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






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