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. Results in a genetically identical inidvidual






2. Way more offspring are produced than by sexual reproduction






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






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






5. Sexual partners chosen based on some characteristics






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






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






8. 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






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






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






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






12. Capable of asexual reproduction; most are not






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






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






15. A subset of a population colonizes a new area






16. The change in a populations genetics






17. Mate choice; one sex chooses their mate






18. Selects for the extremes and against the middle






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






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






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






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






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






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






25. 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






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






27. Change in alleles due to random chance






28. 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






29. Selects for the middle and against the extremes






30. One extreme is selected over the other






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






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






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






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






35. Cells that can turn into other cells






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






37. The organism with the most advantageous traits will survive






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






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






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






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






42. Sometimes different species share common ancestors






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






44. 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






45. Directional selection - Disruptive selection - Stabalizing






46. Form of reproduction more used because it creates Variation






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






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






49. A widely accepted idea with lots of evidence






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