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






2. Selects for the extremes and against the middle






3. Cells that can turn into other cells






4. Change in alleles due to random chance






5. Mate choice; one sex chooses their mate






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






7. A subset of a population colonizes a new area






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






9. Form of reproduction more used because it creates Variation






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






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






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






13. Differences in appearances between the sexes






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. The idea that characteristics can enhance an organisms survival






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

17. A widely accepted idea with lots of evidence






18. 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






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






20. Related organisms have similar development plans






21. The organism with the most advantageous traits will survive






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






23. 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






24. Capable of asexual reproduction; most are not






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






26. Humans selecting certain traits in domestic organisms






27. Sexual partners chosen based on some characteristics






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






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






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






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






32. 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






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






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






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






36. 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






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






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






39. One extreme is selected over the other






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






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






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






43. Results in a genetically identical inidvidual






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






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






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






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






48. The change in a populations genetics






49. Way more offspring are produced than by sexual reproduction






50. Directional selection - Disruptive selection - Stabalizing
