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






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






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






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






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






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






7. Sometimes different species share common ancestors






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






9. Capable of asexual reproduction; most are not






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. Directional selection - Disruptive selection - Stabalizing






12. The idea that characteristics can enhance an organisms survival






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






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






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






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






17. The organism with the most advantageous traits will survive






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. Way more offspring are produced than by sexual reproduction






20. Form of reproduction more used because it creates Variation






21. 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






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






23. Cells that can turn into other cells






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






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






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






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






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






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






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






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






32. A subset of a population colonizes a new area






33. Related organisms have similar development plans






34. 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






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






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 catastrophism(sudden events that lead to extinction - but not in todays time)






38. Closely related organisms have more similar DNA sequences and protein structures






39. 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






40. Selects for the extremes and against the middle






41. Mate choice; one sex chooses their mate






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






43. Results in a genetically identical inidvidual






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






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






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

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






48. Differences in appearances between the sexes






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






50. 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
