Gene activation refers to the process of turning on a specific gene to initiate its expression. There are various synonyms for gene activation, and some of them include gene induction, transcriptional activation, and upregulation of the gene expression. In molecular biology, researchers use different tools and techniques to study gene activation and its role in various biological processes, such as embryonic development, cellular differentiation, and disease formation. These techniques involve the identification of regulatory elements and the use of transcription factors that bind to specific gene sequences to initiate their transcription. The study of gene activation is critical to understanding the molecular basis of life and developing new therapeutic strategies for human diseases.
