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






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






3. Direct competition for mates with the same sex






4. Mate choice; one sex chooses their mate






5. 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






6. Humans selecting certain traits in domestic organisms






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






8. A subset of a population colonizes a new area






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






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






12. Results in a genetically identical inidvidual






13. Capable of asexual reproduction; most are not






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






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






16. The idea that characteristics can enhance an organisms survival






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






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






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






20. A widely accepted idea with lots of evidence






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






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






23. Form of reproduction more used because it creates Variation






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






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






26. Cells that can turn into other cells






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






28. 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






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






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






31. 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






32. 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






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






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






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






36. Sometimes different species share common ancestors






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






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






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

40. The organism with the most advantageous traits will survive






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






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






43. Change in alleles due to random chance






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






45. Directional selection - Disruptive selection - Stabalizing






46. 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






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






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






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






50. Related organisms have similar development plans
