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. 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






2. The idea that characteristics can enhance an organisms survival






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






4. Cells that can turn into other cells






5. 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






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






7. Form of reproduction more used because it creates Variation






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






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






10. 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






11. Direct competition for mates with the same sex






12. 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






13. 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






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






15. Mate choice; one sex chooses their mate






16. Directional selection - Disruptive selection - Stabalizing






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






18. The change in a populations genetics






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






20. A widely accepted idea with lots of evidence






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






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






23. Change in alleles due to random chance






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






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






26. Results in a genetically identical inidvidual






27. Selects for the middle and against the extremes






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






29. One extreme is selected over the other






30. Way more offspring are produced than by sexual reproduction






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






32. Sexual partners chosen based on some characteristics






33. Sometimes different species share common ancestors






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






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






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






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






39. 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






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






41. The organism with the most advantageous traits will survive






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






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






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






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






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

47. Selects for the extremes and against the middle






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






49. Humans selecting certain traits in domestic organisms






50. 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
