DNA sequencing of the entire H. influenzae genomewas completed in 1995. When DNA from the nonpathogenic strain H. influenzae Rd was compared tothat of the pathogenic b strain, eight genes of the fimbrial gene cluster (located between the purE andpepN genes) involved in adhesion of bacteria to hostcells were completely missing from the nonpathogenic strain. What effect would this deletion have oncotransformation of purE and pepN genes using DNAisolated from the nonpathogenic versus the pathogenic strain?
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.

was completed in 1995. When DNA from the nonpathogenic strain H. influenzae Rd was compared to
that of the pathogenic b strain, eight genes of the fimbrial gene cluster (located between the purE and
pepN genes) involved in adhesion of bacteria to host
cells were completely missing from the nonpathogenic strain. What effect would this deletion have on
cotransformation of purE and pepN genes using DNA
isolated from the nonpathogenic versus the pathogenic strain?
