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






2. Humans selecting certain traits in domestic organisms






3. Related organisms have similar development plans






4. One extreme is selected over the other






5. Change in alleles due to random chance






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






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






8. Way more offspring are produced than by sexual reproduction






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






10. Differences in appearances between the sexes






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






12. Directional selection - Disruptive selection - Stabalizing






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






14. Form of reproduction more used because it creates Variation






15. Sometimes different species share common ancestors






16. A subset of a population colonizes a new area






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






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






19. The organism with the most advantageous traits will survive






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






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






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






23. 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






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






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






26. The idea that characteristics can enhance an organisms survival






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






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






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






30. Capable of asexual reproduction; most are not






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






32. Selects for the extremes and against the middle






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






34. 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






35. 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






36. 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






37. 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






38. Sexual partners chosen based on some characteristics






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






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






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






42. Selects for the middle and against the extremes






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






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






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






46. A widely accepted idea with lots of evidence






47. Results in a genetically identical inidvidual






48. The change in a populations genetics






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






50. 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
