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. The change in a populations genetics






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






4. 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






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






6. 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






7. Selects for the extremes and against the middle






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






9. 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






10. A subset of a population colonizes a new area






11. 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






12. Cells that can turn into other cells






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






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

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






16. Results in a genetically identical inidvidual






17. Selects for the middle and against the extremes






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






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






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






21. 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






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






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






24. Directional selection - Disruptive selection - Stabalizing






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






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






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






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






29. A widely accepted idea with lots of evidence






30. The organism with the most advantageous traits will survive






31. Capable of asexual reproduction; most are not






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






33. Humans selecting certain traits in domestic organisms






34. Direct competition for mates with the same sex






35. 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






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






37. Sexual partners chosen based on some characteristics






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






39. Change in alleles due to random chance






40. Related organisms have similar development plans






41. Mate choice; one sex chooses their mate






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






43. The idea that characteristics can enhance an organisms survival






44. One extreme is selected over the other






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






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






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






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






49. 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






50. Sometimes different species share common ancestors
