Test your basic knowledge |

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






2. Selects for the extremes and against the middle






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






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






5. The change in a populations genetics






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






7. 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






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






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






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






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






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






13. Cells that can turn into other cells






14. 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






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

16. Selects for the middle and against the extremes






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






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






19. Change in alleles due to random chance






20. 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






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






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






23. Differences in appearances between the sexes






24. One extreme is selected over the other






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






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






27. Direct competition for mates with the same sex






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






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






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






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






32. Sometimes different species share common ancestors






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






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






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






36. A widely accepted idea with lots of evidence






37. Capable of asexual reproduction; most are not






38. 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






39. Related organisms have similar development plans






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






41. Sexual partners chosen based on some characteristics






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






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






44. Way more offspring are produced than by sexual reproduction






45. Form of reproduction more used because it creates Variation






46. Mate choice; one sex chooses their mate






47. The idea that characteristics can enhance an organisms survival






48. A subset of a population colonizes a new area






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






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