You isolate bacteria from several different pools at the recreation center. Curious about which bacteria likely have a common ancestor with your reference pool (the Buffalo-pool), you BLAST the 16S ribosomal gene from the Buffalo pool bacteria against the 16S ribosomal genes from the other pools. The results are shown below. Which of the bacteria likely have a common ancestor with the Buffalo-pool bacteria? Use e as a cutoff for homology. Organism Dive-well bacteria Competition-pool bacterial Practice-pool bacteria Puddle bacteria U Puddle bacteria Practice-pool bacteria Competition-pool bacteria Dive-well bacteria E-value 9e-175 -300 8e 4e-2 4
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.
