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






2. Mate choice; one sex chooses their mate






3. Cells that can turn into other cells






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






5. 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






6. Directional selection - Disruptive selection - Stabalizing






7. 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






8. One extreme is selected over the other






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






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






11. The idea that characteristics can enhance an organisms survival






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






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






14. A widely accepted idea with lots of evidence






15. Selects for the middle and against the extremes






16. Way more offspring are produced than by sexual reproduction






17. Capable of asexual reproduction; most are not






18. Direct competition for mates with the same sex






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






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






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






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






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






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






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






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






27. Sexual partners chosen based on some characteristics






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






29. Humans selecting certain traits in domestic organisms






30. The change in a populations genetics






31. 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






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






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






34. Selects for the extremes and against the middle






35. Form of reproduction more used because it creates Variation






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






37. 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






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






39. Related organisms have similar development plans






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






41. The organism with the most advantageous traits will survive






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






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


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






45. 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






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






47. 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






48. 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






49. A subset of a population colonizes a new area






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