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. Related organisms have similar development plans






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






3. 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






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






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






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






7. 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






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






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






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






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






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






13. Selects for the extremes and against the middle






14. Results in a genetically identical inidvidual






15. 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






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






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






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






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






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






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






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






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






25. Sometimes different species share common ancestors






26. Humans selecting certain traits in domestic organisms






27. Directional selection - Disruptive selection - Stabalizing






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






29. 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






30. 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






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






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






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






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






35. 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






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






37. The organism with the most advantageous traits will survive






38. Differences in appearances between the sexes






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






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






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






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






43. Selects for the middle and against the extremes






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






45. One extreme is selected over the other






46. Form of reproduction more used because it creates Variation






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






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






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






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