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. Sexual partners chosen based on some characteristics






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






3. Selects for the middle and against the extremes






4. 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






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






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






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






8. Sometimes different species share common ancestors






9. A subset of a population colonizes a new area






10. 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






11. 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






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






13. 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






14. A widely accepted idea with lots of evidence






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






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






17. Results in a genetically identical inidvidual






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






19. Related organisms have similar development plans






20. Change in alleles due to random chance






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

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






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






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






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. Differences in appearances between the sexes






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






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






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






31. Way more offspring are produced than by sexual reproduction






32. Mate choice; one sex chooses their mate






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






34. Humans selecting certain traits in domestic organisms






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






36. Cells that can turn into other cells






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






38. Form of reproduction more used because it creates Variation






39. Capable of asexual reproduction; most are not






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






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






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






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






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






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






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






48. Selects for the extremes and against the middle






49. 1.edits existing variation by using the material it has(variation that exists in population/ no new traits created by natural selection) 2. Has historical constraints(change in old structures) 3. Adaptations are compromises (good for one thing - bad






50. The change in a populations genetics
