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






2. A widely accepted idea with lots of evidence






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






4. 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






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






6. A subset of a population colonizes a new area






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






8. Form of reproduction more used because it creates Variation






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






10. Direct competition for mates with the same sex






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






12. 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






13. Related organisms have similar development plans






14. Capable of asexual reproduction; most are not






15. Results in a genetically identical inidvidual






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






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






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






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






21. The idea that characteristics can enhance an organisms survival






22. The organism with the most advantageous traits will survive






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






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






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






26. One extreme is selected over the other






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






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






29. 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






30. The change in a populations genetics






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


32. 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






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






34. Sexual partners chosen based on some characteristics






35. Cells that can turn into other cells






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






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






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






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






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






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






42. Differences in appearances between the sexes






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






44. 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






45. 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






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






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






48. Mate choice; one sex chooses their mate






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






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