Summary Introduction

To review:

The use of either genomic DNA or cDNA (complementary deoxyribonucleic acid) in an expression vector during cloning.

Introduction:

The extra-chromosomal DNA (deoxyribonucleic acid) present within the bacterial cell is termed as a vector. It replicatesindependently and exists separately from the main chromosomal DNAin the cell. A vector can be recombinant (contain a foreign gene that forms copies of the gene) or expression (express the gene in the cell).
