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. 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






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






3. 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






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






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






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






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






8. 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






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






10. Directional selection - Disruptive selection - Stabalizing






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






12. Mate choice; one sex chooses their mate






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






14. The organism with the most advantageous traits will survive






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






16. 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






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






18. Selects for the middle and against the extremes






19. Sometimes different species share common ancestors






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






21. The change in a populations genetics






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






23. Way more offspring are produced than by sexual reproduction






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






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






26. Capable of asexual reproduction; most are not






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






28. Cells that can turn into other cells






29. 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






30. Humans selecting certain traits in domestic organisms






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






32. One extreme is selected over the other






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. A subset of a population colonizes a new area






35. 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






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






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






38. A widely accepted idea with lots of evidence






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






40. Form of reproduction more used because it creates Variation






41. Related organisms have similar development plans






42. The idea that characteristics can enhance an organisms survival






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






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






45. Results in a genetically identical inidvidual






46. 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






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






48. Change in alleles due to random chance






49. Differences in appearances between the sexes






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