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






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






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






4. The change in a populations genetics






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






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






8. Direct competition for mates with the same sex






9. Capable of asexual reproduction; most are not






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






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






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






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






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






15. 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






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






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






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






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. Mate choice; one sex chooses their mate






21. Sexual partners chosen based on some characteristics






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






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






24. Humans selecting certain traits in domestic organisms






25. Directional selection - Disruptive selection - Stabalizing






26. Sometimes different species share common ancestors






27. Differences in appearances between the sexes






28. Related organisms have similar development plans






29. 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






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






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






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






33. Results in a genetically identical inidvidual






34. 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






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






36. 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






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






38. Cells that can turn into other cells






39. 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






40. 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






41. A widely accepted idea with lots of evidence






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






43. Form of reproduction more used because it creates Variation






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






45. A subset of a population colonizes a new area






46. The organism with the most advantageous traits will survive






47. Selects for the middle and against the extremes






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






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






50. Selects for the extremes and against the middle
