Expression of the operon ultimately results in the synthesis of the repressor (Q) and co-repressor (W) proteins. What happens to regulation/control of the operon upon accumulation of Q and W proteins?
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.
Expression of the operon ultimately results in the synthesis of the repressor (Q) and co-repressor (W) proteins. What happens to regulation/control of the operon upon accumulation of Q and W proteins?
A repressor is a protein that turns off the expression of one or more genes. The repressor protein works by binding to the promoter region of the gene, inhibting the access of RNA polymerase thereby preventing the production of messenger RNA (mRNA). A corepressor is a molecule that can bind to the repressor and make it bind to the operator tightly, which decreases transcription.
