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. Mate choice; one sex chooses their mate






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






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






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






5. A widely accepted idea with lots of evidence






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






7. The change in a populations genetics






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






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






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






11. A subset of a population colonizes a new area






12. Capable of asexual reproduction; most are not






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






14. The organism with the most advantageous traits will survive






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






16. The idea that characteristics can enhance an organisms survival






17. One extreme is selected over the other






18. Sexual partners chosen based on some characteristics






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






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






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






22. Sometimes different species share common ancestors






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






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






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






26. Selects for the extremes and against the middle






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






28. Selects for the middle and against the extremes






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






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






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. 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






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






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






35. Change in alleles due to random chance






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






37. Directional selection - Disruptive selection - Stabalizing






38. 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






39. Direct competition for mates with the same sex






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






41. 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






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






43. Humans selecting certain traits in domestic organisms






44. Cells that can turn into other cells






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






46. Differences in appearances between the sexes






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






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






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






50. Results in a genetically identical inidvidual
