What Are Expression Vectors?
In the 21st century, microbiologists work on ways to alter genes and cells. They are experimenting with everything from genetic cures for diseases to altering the evolutionary process. Vectors in general and specifically expression vectors are a major contributor to this experimentation.DefinitionA vector is a DNA molecule that takes foreign genetic material and moves it to another cell. All genetically engineered vectors have a multicloning site, a selectable marker, and an origin of replication.Expression in MicrobiologyAccording to “Tabors Cyclopedic Medical Dictionary,” expression in microbiology is the process that determines which genes are transcribed and translated into mRNA and proteins in a cell. Gene expression occurs in all living cells.Expression VectorsAn expression vector has been created to express a cloned gene in a certain cell type. This alters the DNA in the receiving cell.Use of Expression VectorsExpression vectors are used to create a mutation at a predefined posi
