An expression vector is a plasmid or other vector used to introduce and express a specific gene within a host cell, often for the purpose of producing a protein. These vectors are essential tools in molecular biology and biotechnology. Key features of expression vectors include: 1. **Promoter Region**: This is a sequence that drives the transcription of the gene of interest. Depending on the host organism (bacteria, yeast, mammalian cells, etc.), different promoters may be used to ensure optimal expression levels.
