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






2. A subset of a population colonizes a new area






3. 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






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






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






6. Mate choice; one sex chooses their mate






7. A widely accepted idea with lots of evidence






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






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






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






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






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






13. Form of reproduction more used because it creates Variation






14. Capable of asexual reproduction; most are not






15. Change in alleles due to random chance






16. Results in a genetically identical inidvidual






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






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






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






20. Related organisms have similar development plans






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






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






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






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






25. Direct competition for mates with the same sex






26. Cells that can turn into other cells






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






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






29. 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






30. 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






31. 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






32. The change in a populations genetics






33. Humans selecting certain traits in domestic organisms






34. The idea that characteristics can enhance an organisms survival






35. Selects for the extremes and against the middle






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






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






38. 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






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






40. One extreme is selected over the other






41. Differences in appearances between the sexes






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






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






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






46. 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






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






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






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






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