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






2. The idea that characteristics can enhance an organisms survival






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






4. 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






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






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






7. The change in a populations genetics






8. 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






9. Capable of asexual reproduction; most are not






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






11. Cells that can turn into other cells






12. Sexual partners chosen based on some characteristics






13. Change in alleles due to random chance






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






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






16. Direct competition for mates with the same sex






17. Differences in appearances between the sexes






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






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






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






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






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






23. 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






24. 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






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






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






27. Sometimes different species share common ancestors






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






29. Selects for the extremes and against the middle






30. A subset of a population colonizes a new area






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






32. Directional selection - Disruptive selection - Stabalizing






33. Humans selecting certain traits in domestic organisms






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

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






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






37. Selects for the middle and against the extremes






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






39. One extreme is selected over the other






40. 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






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. A widely accepted idea with lots of evidence






43. Mate choice; one sex chooses their mate






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






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






46. 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






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






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






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






50. The organism with the most advantageous traits will survive
