Gene

A gene is a segment of DNA that contains the instructions for making proteins, which are essential for the structure and function of living organisms. Genes determine various traits, such as eye color, height, and susceptibility to certain diseases. They are passed from parents to offspring, contributing to hereditary characteristics. Each gene has a specific location on a chromosome, and humans have approximately 20,000 to 25,000 genes that work together to shape our biological makeup. In essence, genes are the building blocks of life, guiding how we grow and function.
