Evolution Quote by Robert M. Sapolsky
““here’s a highly simplified version of the next chapter’s focus on genes: (a) each gene specifies the production of a specific type of protein; (b) a gene has to be “activated” for the protein to be produced and “deactivated” to stop producing it—thus genes come with on/off switches; (c) every cell in our bodies contains the same library of genes; (d) during development, the pattern of which genes are activated determines which cells turn into nose, which into toes, and so on; (e) forever after, nose, toes, and other cells retain distinctive patterns of gene activation.””

Genes act as instructions and switches that turn proteins on or off, shaping cell identity and body parts throughout development and life.
In simple terms: Genes control protein production and cell fate.
