Definition
Gene expression is the process by which information from a gene is used to synthesize a functional gene product, typically a protein, while cell differentiation is the biological process through which a less specialized cell becomes a more specialized cell type, often involving changes in gene expression patterns that determine the cell's function and identity.
Summary
Gene expression is a fundamental biological process that allows cells to produce proteins necessary for life. It involves two main stages: transcription, where DNA is converted into messenger RNA (mRNA), and translation, where mRNA is used to synthesize proteins. This process is crucial for cell function and is tightly regulated to ensure that the right proteins are made at the right times. Cell differentiation is the process by which unspecialized cells, such as stem cells, develop into specialized cells with distinct functions. This specialization is essential for the formation of tissues and organs in multicellular organisms. Understanding gene expression and cell differentiation is vital for advancements in medical therapies, genetic engineering, and regenerative medicine.
