Explanation:

Reading Question 2:

Mice are useful animal models because they have a relatively short generation time (allowing quick breeding for experiments) and share many genetic and physiological similarities with humans (e.g., similar organ systems, genetic makeup for studying diseases). These biological traits make them ideal for research in fields like genetics, medicine, and pharmacology.

The p53 gene in mammals is a tumor - suppressor gene. Its main function is to regulate the cell cycle, preventing cells with damaged DNA from dividing uncontrollably. It can also trigger apoptosis (programmed cell death) in cells with severe DNA damage, thereby reducing the risk of cancer development.

Answer:

1. Short generation time (enables rapid breeding for experimental studies).
2. High genetic and physiological similarity to humans (useful for studying human - related diseases and biological processes).
