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. 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






2. Capable of asexual reproduction; most are not






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






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






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






6. Humans selecting certain traits in domestic organisms






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






8. Way more offspring are produced than by sexual reproduction






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






10. Sexual partners chosen based on some characteristics






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






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






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






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






15. Direct competition for mates with the same sex






16. Change in alleles due to random chance






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






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






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. Related organisms have similar development plans






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






22. Selects for the extremes and against the middle






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






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






25. 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






26. Cells that can turn into other cells






27. The change in a populations genetics






28. The idea that characteristics can enhance an organisms survival






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






30. Differences in appearances between the sexes






31. Directional selection - Disruptive selection - Stabalizing






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






33. A subset of a population colonizes a new area






34. 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






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






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






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. Sometimes different species share common ancestors






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

40. 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






41. 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






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






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






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






45. Form of reproduction more used because it creates Variation






46. 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






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






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






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






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