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.
- Certain strains of bacteria that were killed by the antibiotic penicillin in the past are now resistant. The probable explanation for this is that
|
the reproductive rate must have increased naturally. |
||
|
a mutation for resistance occurred that was passed on to succeeding generations because it had high survival value. |
||
|
the strains have become resistant because they needed to do so for survival. |
||
|
individual bacteria gradually became tolerant to increasing levels of penicillin over some time. |
