EXPRESSION VECTOR Meaning and
Definition
-
An expression vector is a type of DNA molecule that is engineered to carry and produce specific genes in cells. It functions as a vehicle for the transfer and expression of foreign genes in host organisms, particularly in biotechnology and genetic engineering applications.
Expression vectors usually consist of several essential components that enable the efficient transfer and expression of genes. These components typically include a promoter sequence, which initiates gene transcription, a coding sequence that contains the gene of interest, and a terminator sequence that signals the end of gene transcription. Additionally, these vectors can have other regulatory elements such as enhancers or operators, which may help control the level of gene expression.
The use of expression vectors is crucial in various applications, such as recombinant protein production, genetic therapies, and the study of gene functions. By cloning genes into expression vectors, scientists can introduce them into host cells, which then produce the desired gene products. This enables the production of proteins or RNA molecules that may have therapeutic value, as well as facilitating the analysis of gene function and regulation.
Overall, expression vectors play a pivotal role in genetic engineering, allowing researchers to manipulate and express specific genes efficiently in various host organisms for diverse scientific and practical purposes.

Etymology of EXPRESSION VECTOR
The word "expression vector" is a compound term made up of two parts: "expression" and "vector".
1. Expression: The term "expression" in molecular biology refers to the process by which genetic information (DNA) is used to synthesize a functional gene product, such as a protein. In this context, "expression" refers to the transcription of DNA into RNA and the translation of RNA into protein. The word "expression" originated from the Latin word "expressio", which means "to press out" or "to make manifest".
2. Vector: In molecular biology, a "vector" is a vehicle used to carry and deliver foreign genetic material into a host cell. It can be a plasmid, virus, or other genetic element. The term "vector" originates from the Latin word "vehere", which means "to carry" or "to transport".
