Animals of the order arthropoda, like lizards, amphibians, and many other animals that shed their skin, are indeterminate growers

There are many reasons why researchers use mice as animal models in science and medicine. A huge reason why mice are used is that their genetics and behavioral characteristics are very close to humans. So, having an animal model for Huntington’s Disease would help scientists be able to study the disease further and make advancements in treatment options in a far less costly and a much safer way than studying it in humans. Mice as animal models can also help in a huge way because their lifespans are very short compared to humans (they only live about 2-3 years). This allows scientists to be able to study the affects of the gene over many generations in a much shorter amount of time.
