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.
How can transposons be used in bacterial genetics?
Transposable elements are known as stretches of DNA molecules and they can move from one place to another place. In bacteria, insertion sequences (IS) and transposons are two important types of transposable elements. Transposons contain genes encoding the transposase enzyme, which is essential for transposition. In addition, they carry short inverted terminal repeats at both ends and these sequences are also essential for transposition. The process of the movement of the transposons is known as transposition.
