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






2. Results in a genetically identical inidvidual






3. Humans selecting certain traits in domestic organisms






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






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






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






7. The idea that characteristics can enhance an organisms survival






8. 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






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






10. 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






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






12. One extreme is selected over the other






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






14. Differences in appearances between the sexes






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






16. Directional selection - Disruptive selection - Stabalizing






17. The organism with the most advantageous traits will survive






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






19. Selects for the extremes and against the middle






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






21. Cells that can turn into other cells






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






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






24. A widely accepted idea with lots of evidence






25. Form of reproduction more used because it creates Variation






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






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






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






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






31. 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






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






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






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






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






37. 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






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






39. Capable of asexual reproduction; most are not






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






41. Way more offspring are produced than by sexual reproduction






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






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






44. Change in alleles due to random chance






45. Direct competition for mates with the same sex






46. Sexual partners chosen based on some characteristics






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






48. Mate choice; one sex chooses their mate






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


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