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






2. 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






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






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






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






6. Mate choice; one sex chooses their mate






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






8. 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






9. 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






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






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

12. 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






13. 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






14. 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






15. Selects for the middle and against the extremes






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






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






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






19. Sometimes different species share common ancestors






20. Cells that can turn into other cells






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






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






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






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






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






26. Form of reproduction more used because it creates Variation






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






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






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






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






31. A subset of a population colonizes a new area






32. The idea that characteristics can enhance an organisms survival






33. Direct competition for mates with the same sex






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






35. One extreme is selected over the other






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. The organism with the most advantageous traits will survive






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






40. Sexual partners chosen based on some characteristics






41. 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






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






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






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






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






46. Change in alleles due to random chance






47. A widely accepted idea with lots of evidence






48. The change in a populations genetics






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






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