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






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






3. Mate choice; one sex chooses their mate






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. A widely accepted idea with lots of evidence






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






7. Differences in appearances between the sexes






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






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






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






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






13. 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






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






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






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






17. Change in alleles due to random chance






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






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






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






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






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






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






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






25. Related organisms have similar development plans






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






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






28. Way more offspring are produced than by sexual reproduction






29. Sexual partners chosen based on some characteristics






30. The organism with the most advantageous traits will survive






31. Sometimes different species share common ancestors






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

33. A subset of a population colonizes a new area






34. Selects for the extremes and against the middle






35. Direct competition for mates with the same sex






36. 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






37. The idea that characteristics can enhance an organisms survival






38. 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






39. 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






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






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






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






43. 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






44. Capable of asexual reproduction; most are not






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






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






48. 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






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






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