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


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






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






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






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






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






7. Directional selection - Disruptive selection - Stabalizing






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






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






10. Humans selecting certain traits in domestic organisms






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






12. 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






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






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






15. Capable of asexual reproduction; most are not






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






17. Differences in appearances between the sexes






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






19. 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






20. A widely accepted idea with lots of evidence






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






22. 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






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






24. 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






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






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






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






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






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






30. Selects for the extremes and against the middle






31. A subset of a population colonizes a new area






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






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






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






35. Sometimes different species share common ancestors






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






37. Cells that can turn into other cells






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






39. 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






40. 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






41. Selects for the middle and against the extremes






42. Form of reproduction more used because it creates Variation






43. Results in a genetically identical inidvidual






44. 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






45. The change in a populations genetics






46. Change in alleles due to random chance






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






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






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






50. Mate choice; one sex chooses their mate
