You identify a new bacterial species in the koi pond between the Curry Student Center and Robinson Hall and decide to name it NE koili. You analyze the genome sequence of NE koili and find that the NE koili genome contains cas genes and pieces of various bacteriophage genomes separated by unique repeats. You roommate is baffled by this observation. Having covered this topic in BIOL2299, explain to your roommate why there are pieces of phage DNA in a bacterial genome. In your answer, include the role of cas nuclease.
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.
