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






2. 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






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






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






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






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






7. Related organisms have similar development plans






8. Form of reproduction more used because it creates Variation






9. A widely accepted idea with lots of evidence






10. Selects for the middle and against the extremes






11. One extreme is selected over the other






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






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






14. Mate choice; one sex chooses their mate






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






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






17. Way more offspring are produced than by sexual reproduction






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






19. The organism with the most advantageous traits will survive






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






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


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






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






24. Sexual partners chosen based on some characteristics






25. Selects for the extremes and against the middle






26. 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






27. 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






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






29. Capable of asexual reproduction; most are not






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






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






32. Results in a genetically identical inidvidual






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






34. 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






35. The idea that characteristics can enhance an organisms survival






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






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






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






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






40. A subset of a population colonizes a new area






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






42. Direct competition for mates with the same sex






43. 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






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






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






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






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






48. Cells that can turn into other cells






49. 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






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