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






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






3. Traits that are neither advantageous nor disadvantageous; there is no selection






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






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






6. 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






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






8. Change in alleles due to random chance






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






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






11. Related organisms have similar development plans






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






13. A subset of a population colonizes a new area






14. A widely accepted idea with lots of evidence






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






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. Direct competition for mates with the same sex






18. One extreme is selected over the other






19. Mate choice; one sex chooses their mate






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






21. The idea that characteristics can enhance an organisms survival






22. Sometimes different species share common ancestors






23. The change in a populations genetics






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






25. Cells that can turn into other cells






26. Differences in appearances between the sexes






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






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






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






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






31. 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






32. Results in a genetically identical inidvidual






33. Way more offspring are produced than by sexual reproduction






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






35. Sexual partners chosen based on some characteristics






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






37. Form of reproduction more used because it creates Variation






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






39. Directional selection - Disruptive selection - Stabalizing






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






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






42. 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






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






44. The screening of embryos for genetic disorders; done in In Vitro fertilization(fertilization in a petri dish); PGD removes one cell from the embryo and screens it genetically; embryos with disorders are discarded - ones without are kept and implanted






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






46. Capable of asexual reproduction; most are not






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


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






49. 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






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