Give the examples of plasmid vector used in rDNA technology.

1. Vectors in genetic engineering is usually a DNA segment used as a carrier for transferring a selected DNA into living cells.
2.  The two examples of vector are plasmid vectors and bacteriophage vector.

 In recombinant DNA technology, there are various components one of them is the vector, it is the most important component of recombinant DNA technology. Vectors are the molecular carriers that carry the gene of interest to the host cells. Vectors can replicate independently without the control of chromosomal DNA. In this method, a foreign short piece of DNA which is mainly the gene of interest is been inserted to the vector. Then after doing this, this vector is being transformed into the bacterial cell host mainly E. coli cells, so that it can replicate inside the host cells and after that protein of interest can be isolated from it. The two examples of the vector can be a bacteriophage vector and a plasmid vector.
