You are interested in a eukaryotic protein involved in immunity, and you are attempting to express this protein in E. coli in order to produce large amounts of the protein. You have identified the gene and place a copy of the gene on a plasmid
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.
. You are interested in a eukaryotic protein involved in immunity, and you are attempting to express this protein in E. coli in order to produce large amounts of the protein. You have identified the gene and place a copy of the gene on a plasmid in E. coli next to a bacterial promoter sequence. You determine that lots of mRNA is made from your gene in your E. coli system, but the protein produced is larger and doesn't have the same properties as the eukaryotic protein you expected. What mistake have you made and how can you fix it?
