Genes意思

"Genes" is a term derived from the Greek word "genes", which means "born" or "begotten". In the context of biology and genetics, genes are defined as the fundamental physical and functional units of heredity. They are made up of deoxyribonucleic acid (DNA), which is a complex molecule that contains the genetic instructions used in the development and functioning of all known living organisms.

Genes are segments of DNA that code for specific proteins, which are essential for the structure, function, and regulation of the body's cells, tissues, and organs. These proteins determine the characteristics of an organism, such as eye color, hair color, height, and susceptibility to diseases. When a cell divides, the genes are replicated and passed on to the new cell, ensuring the continuity of life.

Genes can be thought of as blueprints for the proteins that drive the chemistry of life. They are responsible for the transmission of characteristics or traits from one generation to the next, and their study is crucial in understanding the mechanisms of inheritance, disease, and evolution.
