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.
Explain how certain bacterial species preferentially take up DNA from their own species?
The process that illustrates the preferential uptake of DNA by the bacterial species from their own species is known as transformation. This explains the genetic alteration as a result of the direct uptake and incorporation of exogenous genetic material via the cell membrane. It is one of the defined processes of horizontal gene transfer.
It is given that " certain bacterial species preferentially take up DNA from their own species".
This statement is true for Streptococcus pneumoniae and several human pathogens.
