Understanding Genes and Their Functions

The video explains how genes, found in every cell, define our biological uniqueness. It details the structure of cells, highlighting the role of DNA and genes in directing bodily functions through protein encoding. Genes are responsible for building body structures, directing bodily actions, supporting functions, and influencing personal traits. With 20,000 to 30,000 genes in the human body, understanding their functions and interactions remains a significant research focus.
