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. Sexual partners chosen based on some characteristics






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






3. 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






4. Way more offspring are produced than by sexual reproduction






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






6. The change in a populations genetics






7. Results in a genetically identical inidvidual






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






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






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






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






12. Differences in appearances between the sexes






13. The organism with the most advantageous traits will survive






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






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






16. 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






17. Capable of asexual reproduction; most are not






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






19. Change in alleles due to random chance






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






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






22. A subset of a population colonizes a new area






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






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






25. Selects for the extremes and against the middle






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






27. Directional selection - Disruptive selection - Stabalizing






28. Sometimes different species share common ancestors






29. A widely accepted idea with lots of evidence






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






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






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






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






34. 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






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






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






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






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






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






40. Cells that can turn into other cells






41. 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






42. Selects for the middle and against the extremes






43. 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






44. One extreme is selected over the other






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






46. 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






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

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






49. Humans selecting certain traits in domestic organisms






50. 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
