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






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






3. Direct competition for mates with the same sex






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






5. 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






6. Related organisms have similar development plans






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






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






9. Differences in appearances between the sexes






10. Sexual partners chosen based on some characteristics






11. 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






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






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






14. Directional selection - Disruptive selection - Stabalizing






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






16. 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






17. The idea that characteristics can enhance an organisms survival






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






19. A subset of a population colonizes a new area






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






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






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






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

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






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






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






27. 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






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






29. The change in a populations genetics






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






31. Way more offspring are produced than by sexual reproduction






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






33. 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






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






35. Humans selecting certain traits in domestic organisms






36. 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






37. 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






38. A widely accepted idea with lots of evidence






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






40. Results in a genetically identical inidvidual






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






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






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






44. One extreme is selected over the other






45. Capable of asexual reproduction; most are not






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






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






48. Mate choice; one sex chooses their mate






49. Selects for the extremes and against the middle






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