The collection covers various facets of gene expression and its regulation, focusing on molecular biology concepts such as the mechanisms of transcription and translation, epigenetics, and gene therapies. It encompasses insights into eukaryotic and prokaryotic gene regulation, the implications of gene expression on traits and diseases, and the growing significance of projects like single-cell transcriptomics in understanding human biology. Additionally, there is exploration into environmental impacts on gene expression, particularly in relation to agriculture and health.
