What is Bacterial Stress Response?

Bacteria can survive under varied conditions (called as Bacterial Stress Response), and to overcome adverse conditions, the changes must be sensed by bacteria and mount reactions in protein activity and gene expression. The stress reaction in bacteria involves a system of components that behave against the stimulation. Compounds can respond simultaneously to many different stresses, and […]

Endoplasmic Reticulum : Basics and Functions

According to Dallmer (1966), Endoplasmic Reticulum is originated from the plasma membrane by the investigation. According to Derobertis (1970), the ER originates from the nuclear envelope. The Endoplasmic Reticulum (ER) is a strikingly complex structure within the cell and has three morphologically distinct regions: Sheets of the nuclear envelope A network of interconnected peripheral ER tubules Peripheral ER sheets […]
