You perform several tests on an unidentified bacterial species and get the results below. Based on the test results and the bacterial table, you narrow down the identity to two possible bacteria. Which test should you now do with these bacteria to narrow down the possibilities to just one bacterial species from the bacterial table? (In other words: knowing the results from which test would let you identify these bacteria?) Gram reaction result: Citrate Test (Tube B): O Nitrate reduction test O Motility test MSA plate O Glucose fermentation test
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.
