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. The change in a populations genetics






2. A widely accepted idea with lots of evidence






3. One extreme is selected over the other






4. Sexual partners chosen based on some characteristics






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






6. 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






7. Results in a genetically identical inidvidual






8. Differences in appearances between the sexes






9. The idea that characteristics can enhance an organisms survival






10. 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






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






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






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






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






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






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






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






18. Selects for the middle and against the extremes






19. Humans selecting certain traits in domestic organisms






20. Form of reproduction more used because it creates Variation






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






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






23. 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






24. Mate choice; one sex chooses their mate






25. Way more offspring are produced than by sexual reproduction






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






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






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






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






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






32. Capable of asexual reproduction; most are not






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






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






35. Change in alleles due to random chance






36. 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






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






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. Related organisms have similar development plans






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






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






42. 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






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






44. The organism with the most advantageous traits will survive






45. Selects for the extremes and against the middle






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






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






48. Cells that can turn into other cells






49. 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






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