Bacteria exchange DNA by several processes Partial genome | transfer by DNA uptake Transformation Conjugation Plasmids Conjugation Genome Plasmid transfer during conjugation Partial genome transfer during conjugation Virus FIGURE 5-2 Bacterial DNA can be transferred from cell to Transduction cell in four ways: conjugation with plasmid transfer, conjugation with partial genome transfer, Transfer as part of viral genome transformation, and transduction.
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.
In Figure 5-2, in which of the four processes shown can a
complete bacterial genome be transferred from one cell
to another?
