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.
4. What is the name of the process by which bacteria pick up a different organism’s genetic
material?
5. Genetically, how does the original bacterial DNA (plasmid) differ from the final bacterial DNA
molecule? (Do not say, “It is longer.”)
6. Tetracycline is an antibiotic that is prescribed to kill bacterial infections. The transformed
bacterial cell that you created has the tetracycline resistant gene in it. If this cell is placed on a
growth medium with tetracycline, will the bacteria grow or die? Explain.
