Nobel Laureate Linus Pauling famously argued that the structure of DNA was a triple helix. Perhaps he was studying DNA from the fictional Planet Triplon, where that indeed appears to be the case! You perform an elegant experiment based on Meselson and Stahl's PNAS paper from the 1950s to test how DNA on this planet is replicated, and find evidence consistent with a conservative mechanism for replication! Indicate the basics for how this experiment works and clearly draw your results. Contrast with how your results might look if the semiconservative model were correct
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.
