Autosomes perform a wide range of functions in an organism including but not limited to:

• Carrying the genes or genetic codes that are vital for the normal functioning and maintenance of the body
• Regulating various metabolic processes and pathways within the cell such as protein synthesis, energy production, and metabolism of lipids, carbohydrates, and nucleic acid
• Coding for enzymes that catalyze specific biochemical reactions involved in synthesizing cellular components, breaking down nutrients, eliminating waste products, and other metabolic processes 
• Regulating cellular homeostasis, which is crucial for maintaining a stable internal environment resulting in optimal cellular function
• Coding for proteins involved in cellular respiration, a process by which cells convert nutrients to energy
• Facilitating cell signaling pathways, which are essential for cell communication and for coordinating cellular activities
• Encoding proteins involved in producing immune system components, activating immune cells, regulating immune responses, and maintaining immune homeostasis
• Synthesizing, secreting, and regulating hormones, which control various physiological processes such as development, homeostasis, metabolism, growth, and reproduction. 
• Carrying genes responsible for DNA repair and replication mechanisms, which are critical to maintaining the stability and integrity of the genome
• Coding for proteins that ensure the proper formation, structure, and function of cells
• Carrying genes responsible for xenobiotic metabolism, which involves metabolizing and eliminating foreign substances from the body
