To bind plasmid DNA to the silica matrix, the DNA has to be suspended in a chaotropic agent and high salt. This statement is: a. True. b. False. A chaotropic agent removes the monomolecular layer of water molecules attached to the silica membrane, making it possible for DNA to bind to the silica membrane. a. True. b. False 7. The third and fourth-generation DNA sequencing methods do not require shearing DNA molecules into short fragments. a. True. b. False. The annealing reaction's nucleation step is unnecessary because both single- strand plasmid DNA circles are held together. Thus, plasmid DNA reannealing proceeds only by the zippering reaction. a. True. b. False
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.
