For a bacterial exotoxin with a typical A-B type toxin structure, removal of the A portion of the toxin would result in which of the following? The B portion remaining would still be able to bind to the target cell, but would not have toxic effects The remaining B portion would enter the cell and carry out its toxic activity, such as ADP-ribosylation The remaining B portion would cause inhibition of protein synthesis Nothing would happen because the A portion is responsible for binding to the target cell. The remaining B portion would still induce cell lysis
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.
