Abstract
The intricate relationship between environmental factors and genetic expression forms a cornerstone of modern biological and medical research. While the genome provides the blueprint, the environment plays a pivotal role in modulating how genes are expressed, leading to phenotypic variation and influencing health and disease susceptibility. This article explores the mechanisms through which environmental stimuli such as diet, stress, toxins, and climate interact with epigenetic processes like DNA methylation, histone modification, and non-coding RNAs to influence gene expression. Understanding these interactions not only elucidates fundamental biological processes but also enhances the development of targeted therapies and personalized medicine.
