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. The idea that characteristics can enhance an organisms survival






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






3. 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






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


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






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






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






8. Selects for the middle and against the extremes






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






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






11. Direct competition for mates with the same sex






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






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






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






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






16. Results in a genetically identical inidvidual






17. 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






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






19. The change in a populations genetics






20. Directional selection - Disruptive selection - Stabalizing






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






22. Humans selecting certain traits in domestic organisms






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






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






25. A subset of a population colonizes a new area






26. Sometimes different species share common ancestors






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






28. Form of reproduction more used because it creates Variation






29. Differences in appearances between the sexes






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






31. 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






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






33. The organism with the most advantageous traits will survive






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






35. Cells that can turn into other cells






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






37. 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






38. Change in alleles due to random chance






39. 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






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






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






42. Selects for the extremes and against the middle






43. Sexual partners chosen based on some characteristics






44. Related organisms have similar development plans






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






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






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






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






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






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
