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. 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






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






4. 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






5. Selects for the extremes and against the middle






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






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






8. Form of reproduction more used because it creates Variation






9. Sometimes different species share common ancestors






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






11. 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






12. Sexual partners chosen based on some characteristics






13. Related organisms have similar development plans






14. One extreme is selected over the other






15. The change in a populations genetics






16. 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






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






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






19. 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






20. Way more offspring are produced than by sexual reproduction






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






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






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






24. Directional selection - Disruptive selection - Stabalizing






25. Differences in appearances between the sexes






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






27. Change in alleles due to random chance






28. Selects for the middle and against the extremes






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






30. 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






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






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






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






34. Humans selecting certain traits in domestic organisms






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






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






37. The organism with the most advantageous traits will survive






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

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






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






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






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






43. Results in a genetically identical inidvidual






44. Mate choice; one sex chooses their mate






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






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






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






48. A subset of a population colonizes a new area






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






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