Crop legumes are an integral part of sustainable agriculture, as several of these species represent an important protein source for both human and animal populations. Legumes engage in a unique and beneficial interaction with a group of soil bacteria, collectively called rhizobia.
The technology of gene therapy is possible due to extensive DNA research and our resulting understanding of many diseases on the genetic level, and it encompasses several mechanisms such as introducing new genes (gene addition) and inactivating or replacing mutated genes (gene editing).
But the bacteria can sometimes change their behavior and enter the bloodstream, causing chronic localized infections to become acute and potentially fatal. Abell Chair in Molecular and Cellular Biology – and Pengbo Cao, a postdoctoral researcher in Whiteley’s lab, discovered a gene that drives the switch.
Overview of Gene Switch The notion that genes might be turned on and off was discovered several decades ago when studies revealed that E. coli bacteria, as well as lambda bacteriophage, can adapt to the alterations in the composition of their nutrient medium.
Biologics activate certain proteins or cells in your immune system to create specific responses to targets, while many conventional systemic drugs activate the entire immune system in a more generalized manner. It is worth mentioning that in vitro geneexpression requires a suitable host for the production of a specific gene product.
The Hershey-Chase experiment is the historic study that solidified DNA as the carrier of genetic information over protein. At the same time, it was thought that protein was the carrier of genetic information as DNA was too inert of a substance — and was also shielded away in the nucleus — to be able to harbor such a role. Martha Chase.
SARS-CoV-2 is characterized by an outer surface speckled with spike proteins, giving it a crown-like appearance, hence the name “corona,” which is the Latin word for crown. The spike protein is critical for binding to ACE2 receptors on host cells — this interaction mediates the entry of the virus into cells.
