R Plasmid Carbenicillin-resistance Chloramphenicol- resistance gene gene Tetracycline- resistance gene -Pilus-synthesis Origin of replication genes - Origin of transfer FIGURE 8.26 Functional Regions of an R Plasmid Genes conferring resistance to antimicrobial compounds tend to be clustered within a specific region (the top half of the illustrated plasmid), whereas genes involved in replication and conjugative transfer are located on a different region (the bottom half of the illustrated plasmid).
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.
