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






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






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






4. A subset of a population colonizes a new area






5. Related organisms have similar development plans






6. Direct competition for mates with the same sex






7. 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






8. Sexual partners chosen based on some characteristics






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






10. Capable of asexual reproduction; most are not






11. The organism with the most advantageous traits will survive






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






14. One extreme is selected over the other






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






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






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






18. 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






19. The change in a populations genetics






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






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

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






23. 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






24. Way more offspring are produced than by sexual reproduction






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






26. Results in a genetically identical inidvidual






27. 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






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






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






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






31. Humans selecting certain traits in domestic organisms






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






33. Mate choice; one sex chooses their mate






34. 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






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






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






37. Selects for the middle and against the extremes






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






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






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






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






42. 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






43. Sometimes different species share common ancestors






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






45. 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






46. Differences in appearances between the sexes






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






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






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






50. Directional selection - Disruptive selection - Stabalizing
