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. Forms that show how an organisms anatomy change over time






2. Results in a genetically identical inidvidual






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






4. Sexual partners chosen based on some characteristics






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






6. Directional selection - Disruptive selection - Stabalizing






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






8. Capable of asexual reproduction; most are not






9. One extreme is selected over the other






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






11. Differences in appearances between the sexes






12. Form of reproduction more used because it creates Variation






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






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






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






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






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






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






19. The idea that characteristics can enhance an organisms survival






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






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






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






23. 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






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






25. Cells that can turn into other cells






26. 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






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






28. 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






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






30. Way more offspring are produced than by sexual reproduction






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






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






33. Humans selecting certain traits in domestic organisms






34. The organism with the most advantageous traits will survive






35. Change in alleles due to random chance






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






37. Related organisms have similar development plans






38. 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






39. Selects for the extremes and against the middle






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






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

42. 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






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






44. A widely accepted idea with lots of evidence






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






46. Mate choice; one sex chooses their mate






47. 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






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






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






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