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. 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






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






3. The idea that characteristics can enhance an organisms survival






4. Cells that can turn into other cells






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






6. A subset of a population colonizes a new area






7. The organism with the most advantageous traits will survive






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






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






10. Change in alleles due to random chance






11. Selects for the extremes and against the middle






12. 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






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






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






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






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






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






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






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






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






21. Form of reproduction more used because it creates Variation






22. Related organisms have similar development plans






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






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






25. Way more offspring are produced than by sexual reproduction






26. A widely accepted idea with lots of evidence






27. Sometimes different species share common ancestors






28. 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






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






30. 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






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






32. 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






33. Differences in appearances between the sexes






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






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






36. 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






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






38. Results in a genetically identical inidvidual






39. Direct competition for mates with the same sex






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






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






42. Humans selecting certain traits in domestic organisms






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






44. The change in a populations genetics






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






46. Selects for the middle and against the extremes






47. 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






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






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






50. Mate choice; one sex chooses their mate
