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. The change in a populations genetics






2. The screening of embryos for genetic disorders; done in In Vitro fertilization(fertilization in a petri dish); PGD removes one cell from the embryo and screens it genetically; embryos with disorders are discarded - ones without are kept and implanted






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






4. Results in a genetically identical inidvidual






5. Sometimes different species share common ancestors






6. Related organisms have similar development plans






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






8. 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






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






10. 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






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

12. 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






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






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






15. One extreme is selected over the other






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






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






18. Capable of asexual reproduction; most are not






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






20. The idea that characteristics can enhance an organisms survival






21. 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






22. A widely accepted idea with lots of evidence






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






24. Cells that can turn into other cells






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






26. 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






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






28. Form of reproduction more used because it creates Variation






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






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






31. Directional selection - Disruptive selection - Stabalizing






32. 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






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






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






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






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






37. 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






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






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






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






41. Direct competition for mates with the same sex






42. Selects for the middle and against the extremes






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






44. A subset of a population colonizes a new area






45. Selects for the extremes and against the middle






46. Humans selecting certain traits in domestic organisms






47. Differences in appearances between the sexes






48. Sexual partners chosen based on some characteristics






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






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