Here's why:
* Genes provide instructions: Genes contain the blueprint for building proteins, which are the workhorses of our cells. These proteins carry out a vast array of functions, from building structures to regulating processes.
* Environment influences expression: While genes contain the instructions, the environment plays a crucial role in determining which genes are turned on (expressed) and how. This includes factors like:
* Diet: Nutrition can influence gene expression, impacting everything from growth to disease susceptibility.
* Exposure to toxins: Certain chemicals can interact with genes and alter their expression.
* Stress: Stress can trigger hormonal changes that affect gene expression.
* Lifestyle: Exercise, sleep, and social interactions can all impact gene expression.
The interaction between genes and environment is complex and dynamic. This is why identical twins, who share the same genetic code, can still develop differences in traits due to their unique environments.
