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. Sexual partners chosen based on some characteristics






2. Capable of asexual reproduction; most are not






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






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






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






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






7. 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






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






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






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






11. A subset of a population colonizes a new area






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






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






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






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






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






17. One extreme is selected over the other






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






19. Cells that can turn into other cells






20. 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






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

Warning: Invalid argument supplied for foreach() in /var/www/html/basicversity.com/show_quiz.php on line 183


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






23. 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






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






25. Humans selecting certain traits in domestic organisms






26. Selects for the extremes and against the middle






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






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






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






30. 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






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






32. The idea that characteristics can enhance an organisms survival






33. Way more offspring are produced than by sexual reproduction






34. Mate choice; one sex chooses their mate






35. Form of reproduction more used because it creates Variation






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






37. Change in alleles due to random chance






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






39. Results in a genetically identical inidvidual






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






41. Differences in appearances between the sexes






42. Related organisms have similar development plans






43. A widely accepted idea with lots of evidence






44. Sometimes different species share common ancestors






45. The change in a populations genetics






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






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






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






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






50. 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
