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






2. Selects for the extremes and against the middle






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






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






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






6. 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






7. Form of reproduction more used because it creates Variation






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






9. 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






10. Results in a genetically identical inidvidual






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






13. The organism with the most advantageous traits will survive






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






15. Direct competition for mates with the same sex






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






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






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






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






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






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






22. Way more offspring are produced than by sexual reproduction






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






24. 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






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






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






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






28. 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






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






30. Capable of asexual reproduction; most are not






31. The change in a populations genetics






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






33. The idea that characteristics can enhance an organisms survival






34. Humans selecting certain traits in domestic organisms






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






36. Selects for the middle and against the extremes






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






38. Cells that can turn into other cells






39. Sometimes different species share common ancestors






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






41. 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






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


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






44. Mate choice; one sex chooses their mate






45. One extreme is selected over the other






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






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






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






49. Change in alleles due to random chance






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