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






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






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






4. The idea that characteristics can enhance an organisms survival






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






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






7. Capable of asexual reproduction; most are not






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






9. Mate choice; one sex chooses their mate






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






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






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






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






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






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






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






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






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






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






20. Sexual partners chosen based on some characteristics






21. 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






22. Selects for the extremes and against the middle






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






24. A widely accepted idea with lots of evidence






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






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






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






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






29. One extreme is selected over the other






30. Selects for the middle and against the extremes






31. Differences in appearances between the sexes






32. The organism with the most advantageous traits will survive






33. 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






34. Direct competition for mates with the same sex






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






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






37. Sometimes different species share common ancestors






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






40. A subset of a population colonizes a new area






41. The change in a populations genetics






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






43. Form of reproduction more used because it creates Variation






44. 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






45. Related organisms have similar development plans






46. 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






47. Results in a genetically identical inidvidual






48. Humans selecting certain traits in domestic organisms






49. 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






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