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. Mate choice; one sex chooses their mate






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






3. Sexual partners chosen based on some characteristics






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






5. Capable of asexual reproduction; most are not






6. 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






7. The organism with the most advantageous traits will survive






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






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






10. 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






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






12. Selects for the extremes and against the middle






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






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






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






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


17. Form of reproduction more used because it creates Variation






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






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






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






21. Way more offspring are produced than by sexual reproduction






22. The change in a populations genetics






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






24. 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






25. Results in a genetically identical inidvidual






26. A subset of a population colonizes a new area






27. Cells that can turn into other cells






28. Change in alleles due to random chance






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






30. 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






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






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. Humans selecting certain traits in domestic organisms






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






35. 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






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






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






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






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






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






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






42. 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






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






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






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. Related organisms have similar development plans






47. One extreme is selected over the other






48. Selects for the middle and against the extremes






49. Directional selection - Disruptive selection - Stabalizing






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