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. Sometimes different species share common ancestors






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






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






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






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






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






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






9. A subset of a population colonizes a new area






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






11. 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






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






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






14. 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






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






16. Related organisms have similar development plans






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






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






19. Way more offspring are produced than by sexual reproduction






20. One extreme is selected over the other






21. Selects for the middle and against the extremes






22. Capable of asexual reproduction; most are not






23. 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






24. Directional selection - Disruptive selection - Stabalizing






25. Cells that can turn into other cells






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






27. Humans selecting certain traits in domestic organisms






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






29. Form of reproduction more used because it creates Variation






30. 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






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






32. Selects for the extremes and against the middle






33. Change in alleles due to random chance






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






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






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






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






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


39. Sexual partners chosen based on some characteristics






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






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






42. The organism with the most advantageous traits will survive






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






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






45. The idea that characteristics can enhance an organisms survival






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






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






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






49. Mate choice; one sex chooses their mate






50. 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
