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. Cells that can turn into other cells






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






3. The change in a populations genetics






4. Mate choice; one sex chooses their mate






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






6. Differences in appearances between the sexes






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






8. 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






9. Selects for the middle and against the extremes






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






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






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






14. The idea that characteristics can enhance an organisms survival






15. 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






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






17. 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






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






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


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






21. One extreme is selected over the other






22. Direct competition for mates with the same sex






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






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






25. Change in alleles due to random chance






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






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






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






30. Way more offspring are produced than by sexual reproduction






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






32. 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






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






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






35. Capable of asexual reproduction; most are not






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






37. Sometimes different species share common ancestors






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






39. A subset of a population colonizes a new area






40. Directional selection - Disruptive selection - Stabalizing






41. Selects for the extremes and against the middle






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






43. Form of reproduction more used because it creates Variation






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






45. A widely accepted idea with lots of evidence






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






47. Results in a genetically identical inidvidual






48. 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






49. 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






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