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






2. Capable of asexual reproduction; most are not






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






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






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






6. Differences in appearances between the sexes






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






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






9. 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






10. The organism with the most advantageous traits will survive






11. Cells that can turn into other cells






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






13. 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






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






15. 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






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






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






18. Humans selecting certain traits in domestic organisms






19. Way more offspring are produced than by sexual reproduction






20. Directional selection - Disruptive selection - Stabalizing






21. Sometimes different species share common ancestors






22. 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






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






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






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






26. A widely accepted idea with lots of evidence






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






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






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






30. Related organisms have similar development plans






31. A subset of a population colonizes a new area






32. Sexual partners chosen based on some characteristics






33. Form of reproduction more used because it creates Variation






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






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






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






37. 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






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






39. Selects for the middle and against the extremes






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






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






42. Selects for the extremes and against the middle






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






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






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






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






47. The idea that characteristics can enhance an organisms survival






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






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






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