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.
When a gene is expressed to make a protein, it first creates a molecule called pre-mRNA. This pre-mRNA contains parts called exons and introns.
During a process called splicing, the cell deletes the introns from the pre-mRNA. Think of it like trimming the unnecessary bits. What's left after splicing is only the exons, which are then put together to form the final mRNA molecule.
This mature mRNA is like a set of instructions that the cell uses to make the protein. So, after splicing, the introns are edited out, and the exons are kept to guide protein production.
