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. Form of reproduction more used because it creates Variation






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


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






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






6. 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






7. One extreme is selected over the other






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






9. Selects for the extremes and against the middle






10. Sometimes different species share common ancestors






11. 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






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






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






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






15. The change in a populations genetics






16. Humans selecting certain traits in domestic organisms






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






18. Related organisms have similar development plans






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






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






21. 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






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






23. Selects for the middle and against the extremes






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






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






27. Change in alleles due to random chance






28. The idea that characteristics can enhance an organisms survival






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






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






31. 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






32. A widely accepted idea with lots of evidence






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






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






35. Direct competition for mates with the same sex






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






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






38. Differences in appearances between the sexes






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






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






41. A subset of a population colonizes a new area






42. Capable of asexual reproduction; most are not






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






44. Sexual partners chosen based on some characteristics






45. 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






46. Cells that can turn into other cells






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






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






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






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