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 group of interbreeding organisms living in the same place at the same time






2. 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






3. Humans selecting certain traits in domestic organisms






4. 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






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






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






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






8. Change in alleles due to random chance






9. Results in a genetically identical inidvidual






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






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






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






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






14. Selects for the extremes and against the middle






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. Related organisms have similar development plans






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






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


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






20. 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






21. Directional selection - Disruptive selection - Stabalizing






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






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






24. A subset of a population colonizes a new area






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






26. Form of reproduction more used because it creates Variation






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






28. Way more offspring are produced than by sexual reproduction






29. 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






30. Direct competition for mates with the same sex






31. One extreme is selected over the other






32. A widely accepted idea with lots of evidence






33. The organism with the most advantageous traits will survive






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






35. Cells that can become only a few different types of cells; mostly adult stem cells; found in bone marrow - the skin epidermis - etc; can sometimes be turned into Totipotent stem cells






36. 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






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






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






39. Selects for the middle and against the extremes






40. Capable of asexual reproduction; most are not






41. The idea that characteristics can enhance an organisms survival






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






43. Cells that can turn into other cells






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






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






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






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






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






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






50. Mate choice; one sex chooses their mate
