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. A widely accepted idea with lots of evidence






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






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






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






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






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






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






8. 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






9. Results in a genetically identical inidvidual






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






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






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






13. Selects for the extremes and against the middle






14. 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






15. 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






16. Capable of asexual reproduction; most are not






17. One extreme is selected over the other






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






19. A subset of a population colonizes a new area






20. 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






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






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






23. 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






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






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






26. Directional selection - Disruptive selection - Stabalizing






27. Humans selecting certain traits in domestic organisms






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






30. The organism with the most advantageous traits will survive






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






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






33. Selects for the middle and against the extremes






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






35. The idea that characteristics can enhance an organisms survival






36. 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






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






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






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






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






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






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






44. Mate choice; one sex chooses their mate






45. The change in a populations genetics






46. Differences in appearances between the sexes






47. 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






48. Form of reproduction more used because it creates Variation






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


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