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






2. Direct competition for mates with the same sex






3. The idea that characteristics can enhance an organisms survival






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






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






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






7. Mate choice; one sex chooses their mate






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






9. 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






10. 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






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






12. Capable of asexual reproduction; most are not






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






14. 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






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






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


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






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






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






20. Sometimes different species share common ancestors






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






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






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






24. Selects for the extremes and against the middle






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






26. Selects for the middle and against the extremes






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






28. Differences in appearances between the sexes






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






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






31. One extreme is selected over the other






32. A widely accepted idea with lots of evidence






33. Change in alleles due to random chance






34. 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






35. Form of reproduction more used because it creates Variation






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






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






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






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






40. Sexual partners chosen based on some characteristics






41. 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






42. 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






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






44. The organism with the most advantageous traits will survive






45. Cells that can turn into other cells






46. A subset of a population colonizes a new area






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






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






49. Related organisms have similar development plans






50. 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
