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






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






3. Sometimes different species share common ancestors






4. Direct competition for mates with the same sex






5. The organism with the most advantageous traits will survive






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






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






8. The idea that characteristics can enhance an organisms survival






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






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






11. 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






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






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






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






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






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






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






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






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






20. Differences in appearances between the sexes






21. Capable of asexual reproduction; most are not






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






23. A subset of a population colonizes a new area






24. 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






25. 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






26. Related organisms have similar development plans






27. One extreme is selected over the other






28. Selects for the extremes and against the middle






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






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






31. A widely accepted idea with lots of evidence






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






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






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






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






37. Mate choice; one sex chooses their mate






38. 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






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






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






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






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






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






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






45. Change in alleles due to random chance






46. 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






47. Selects for the middle and against the extremes






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






49. 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






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