Why Genetic Studies Rely on the Use of Model Organisms ?

Expert Solution
Step 1-Introduction

All organisms have genetic material in the form of DNA. DNA is the hereditary material that is passed on from the parent to the offspring. DNA contains genes, which encode specific proteins. Proteins are responsible for the visible characteristics of the organism.

Genes control all the metabolic activities in the body. It is important to understand how genes function, which can help scientists cure diseases, trace evolution, etc. For such studies, it is unethical and unfeasible to use humans as models. The obstacle is overcome by the use of animal models.
