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. Related organisms have similar development plans






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






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






5. One extreme is selected over the other






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






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






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






9. 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






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






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






12. Humans selecting certain traits in domestic organisms






13. Results in a genetically identical inidvidual






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






15. Capable of asexual reproduction; most are not






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






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






18. 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






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






20. Sometimes different species share common ancestors






21. 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






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






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






24. Form of reproduction more used because it creates Variation






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






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






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






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






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






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






31. The idea that characteristics can enhance an organisms survival






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

34. A subset of a population colonizes a new area






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






36. Selects for the middle and against the extremes






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






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






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






40. 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






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






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






43. The organism with the most advantageous traits will survive






44. Sexual partners chosen based on some characteristics






45. 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






46. A widely accepted idea with lots of evidence






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






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






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






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