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






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






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






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






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






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






7. The change in a populations genetics






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






9. Mate choice; one sex chooses their mate






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






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






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






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






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






16. Selects for the middle and against the extremes






17. 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






18. Form of reproduction more used because it creates Variation






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






20. Related organisms have similar development plans






21. 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






22. Way more offspring are produced than by sexual reproduction






23. 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






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






25. Differences in appearances between the sexes






26. The organism with the most advantageous traits will survive






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






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






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






30. Sometimes different species share common ancestors






31. 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






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






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






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






35. Capable of asexual reproduction; most are not






36. Results in a genetically identical inidvidual






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






38. A subset of a population colonizes a new area






39. Humans selecting certain traits in domestic organisms






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






41. The idea that characteristics can enhance an organisms survival






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






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






44. Cells that can turn into other cells






45. 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






46. Change in alleles due to random chance






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






48. Direct competition for mates with the same sex






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






50. Sexual partners chosen based on some characteristics
