[Campbell Biology P.510] Which of the following statements about the use of model organisms ... | Practice Question

Which of the following statements about the use of model organisms in genetic research are supported by the text? Select all that apply

  • A: Mice are used as models for human genetic disorders due to significant gene sharing and ethical considerations for human experiments.
  • B: Fruit flies are useful for studying aging due to their distant relation to humans.
  • C: Nematodes (soil worms) have provided extensive information regarding the process of aging.
  • D: Researchers can directly use information on gene expression in human tissues to find genes related to genetic disorders in mice.

Explanation

The text explicitly mentions that mice are used as models due to shared genes and because it would be unethical to perform certain experiments on humans supporting A . It also states that nematodes soil worms have yielded a wealth of information about aging supporting C . Option B is incorrect as fruit flies are mentioned for Parkinson's and alcoholism, not aging. Option D misinterprets the text; researchers use mice to look for genes based on similar affected tissues , not by directly mapping human gene expression to mouse genes.
