Question

Model organisms include unicellular bacteria, yeasts, various plants and vertebrate animals, such as fish and mice. Living models are critical for advancement of scientific knowledge and application to human welfare, since they allow discovery of biological processes in an experimental setting. The best model organisms are small, easy to maintain and manipulate. Short lifespans are helpful, as many generations can be examined. Review the Module Notes and reading and video assignments to prepare for this discussion post.

As a biologist and scientist you work with one specific organism as a model for your research in either embryonic development, aging, or human disease. Please explain the biology of the organism and how it is used in your research. Why did you choose this particular organism over other species?

Answer 1

Question

The rodents are use in medical testing for biological research and I choose this particular organism because:

I. Rodents are easily to maintain in the laboratory.

II. Rodents are relatively inexpensive.

III. Rodents reproduce quickly and have short life span.

IV. Easy to handle.

V. Rodents genetic, behavioural and biological chracaterstics resemble with that of humans.
