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. A widely accepted idea with lots of evidence






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






3. Humans selecting certain traits in domestic organisms






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






5. Selects for the middle and against the extremes






6. Change in alleles due to random chance






7. 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






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






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






10. Sometimes different species share common ancestors






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






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






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






14. Mate choice; one sex chooses their mate






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






16. 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






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






18. Differences in appearances between the sexes






19. Capable of asexual reproduction; most are not






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






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






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






23. The organism with the most advantageous traits will survive






24. 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






25. The change in a populations genetics






26. Cells that can turn into other cells






27. 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






28. Directional selection - Disruptive selection - Stabalizing






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






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






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






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






33. Form of reproduction more used because it creates Variation






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






35. The idea that characteristics can enhance an organisms survival






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






37. Results in a genetically identical inidvidual






38. Selects for the extremes and against the middle






39. Sexual partners chosen based on some characteristics






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






41. A subset of a population colonizes a new area






42. One extreme is selected over the other






43. Direct competition for mates with the same sex






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






45. 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






46. Way more offspring are produced than by sexual reproduction






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






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






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






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