Solution B that was used during the plasmid isolation contains 0.2 M NaOH (see practical manual). Which effect does NaOH have on E. coli DNA A) It denatures genomic DNA and plasmid DNA. B) It denatures genomic DNA and but not plasmid DNA. C) It denatures plasmid DNA but not genomic DNA. D) It denatures neither genomic DNA nor plasmid DNA. E) This is unpredictable. Which statement on the migration of DNA fragments through agarose gels is false A) Small fragments migrate faster than larger fragments because they can move faster through the agarose pores. B) Large fragments migrate faster than small fragments because they carry more negative charges. C) DNA fragments migrate towards the positive pole. D) Supercoiled DNA may migrate significantly different through the gel than linear DNA of equal size. E) The higher the agarose concentration the better the separation of smaller fragments as compared to larger fragments.

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.
