Each cell in your body has a unique identity shaped by gene expression. Cell differentiation occurs when specific genes are activated, leading to diverse cell types, from muscle to nerve cells. Although genetics was once seen as the sole determinant of our traits, we now recognize that environmental factors significantly influence gene expression. Factors such as gender, exposure to chemicals, and substances like alcohol can alter our DNA and affect future generations. This exploration of how gene activation can be influenced highlights the dynamic interaction between our genes and environment.

Each type of cell in your body is different. What makes your cells different?
In each cell, different genes have been activated. When genes are activated, this means that the genes are being “expressed”. Each different cell is expressing a different set of genes. It used to be thought that your genes were your destiny, but now we know that environmental factors can influence gene expression.
