In biotechnology, gene cloning is a crucial technique used in many genetic modification experiments. A vector is normally required to perform this process. The vector commonly used to transform a bacterial host cell is known as a plasmid. Below is the general plasmid map of pBR322. Elaborate the functions of ori, ApR and TeR present in pBR322.

Bacterial Genomics
The study of the morphological, physiological, and evolutionary aspects of the bacterial genome is referred to as bacterial genomics. This subdisciplinary field aids in understanding how genes are assembled into genomes. Further, bacterial or microbial genomics has helped researchers in understanding the pathogenicity of bacteria and other microbes.
Transformation Experiment in Bacteria
In the discovery of genetic material, the experiment conducted by Frederick Griffith on Streptococcus pneumonia proved to be a stepping stone.
Plasmids and Vectors
The DNA molecule that exists in a circular shape and is smaller in size which is capable of its replication is called Plasmids. In other words, it is called extra-chromosomal plasmid DNA. Vectors are the molecule which is capable of carrying genetic material which can be transferred into another cell and further carry out replication and expression. Plasmids can act as vectors.
Vectors are the vehicles that carry genes of interest and transmit into another organism . It is classified into:-
I ) Cloning vector
II ) Expression vector
Out of which, cloning vectors are further classified into:-
a ) Plasmid vector
b ) Bacteriophage vector
c ) Cosmid vector
d ) Artificial chromosome
