Test type Tests for presence of | Accuracy Time to get results RT-PCR test Pieces of the virus's Few false negatives.* Test usually does not need to be repeated. One day to one week RNA genome Antigen test Pieces of viral One hour or less More false negatives than the RT-PCR test. May need other tests to confirm negative proteins (antigens) results. *A false negative is when an active infection is not detected by the test. 11. Imagine you are planning to visit a family member who is a nursing home resident.

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.
