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






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






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






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






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






6. Selects for the middle and against the extremes






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






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






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






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






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






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






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






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






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






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






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






19. Directional selection - Disruptive selection - Stabalizing






20. 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






21. 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






22. Change in alleles due to random chance






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






24. The change in a populations genetics






25. Results in a genetically identical inidvidual






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






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






28. Selects for the extremes and against the middle






29. Differences in appearances between the sexes






30. Mate choice; one sex chooses their mate






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






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






33. Way more offspring are produced than by sexual reproduction






34. Sexual partners chosen based on some characteristics






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






36. The organism with the most advantageous traits will survive






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






38. Humans selecting certain traits in domestic organisms






39. One extreme is selected over the other






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






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






42. 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






43. Cells that can turn into other cells






44. The idea that characteristics can enhance an organisms survival






45. A widely accepted idea with lots of evidence






46. Form of reproduction more used because it creates Variation






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






48. Direct competition for mates with the same sex






49. A subset of a population colonizes a new area






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