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






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






3. 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






4. Selects for the middle and against the extremes






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






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






7. 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






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






9. Way more offspring are produced than by sexual reproduction






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






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






12. Directional selection - Disruptive selection - Stabalizing






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






14. The idea that characteristics can enhance an organisms survival






15. 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






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






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






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






19. 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






20. Results in a genetically identical inidvidual






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






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






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






24. One extreme is selected over the other






25. Cells that can turn into other cells






26. Humans selecting certain traits in domestic organisms






27. Selects for the extremes and against the middle






28. Differences in appearances between the sexes






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






30. 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






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






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






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






34. Related organisms have similar development plans






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






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






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






38. 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






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






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






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






42. Mate choice; one sex chooses their mate






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






44. A widely accepted idea with lots of evidence






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






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






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






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






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

50. A subset of a population colonizes a new area
