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


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






3. Way more offspring are produced than by sexual reproduction






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






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






6. A widely accepted idea with lots of evidence






7. Directional selection - Disruptive selection - Stabalizing






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






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






10. The idea that characteristics can enhance an organisms survival






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






12. A subset of a population colonizes a new area






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






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






15. 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






16. 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






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






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






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






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






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






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






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






24. 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






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






26. Direct competition for mates with the same sex






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






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






29. Mate choice; one sex chooses their mate






30. Cells that can turn into other cells






31. The organism with the most advantageous traits will survive






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






33. Differences in appearances between the sexes






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






36. Sometimes different species share common ancestors






37. Sexual partners chosen based on some characteristics






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






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






40. Humans selecting certain traits in domestic organisms






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






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






43. 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






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






45. 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






46. Results in a genetically identical inidvidual






47. Selects for the middle and against the extremes






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






49. Form of reproduction more used because it creates Variation






50. Related organisms have similar development plans
