Lateral transduction is the process by which very long fragments of bacterial DNA are transferred to another bacterium. So far, this form of transduction has been only described in Staphylococcus aureus, but it can transfer more genes and at higher frequencies than generalized and specialized transduction. In lateral transduction, the prophage ...
English: This is an illustration of the difference between generalized transduction, which is the process of transferring any bacterial gene to a second bacterium through a bacteriophage and specialized transduction, which is the process of moving restricted bacterial genes to a recipient bacterium. While generalized transduction can occur ...
The upstream signaling pathway is triggered by the binding of a signaling molecule, a ligand, to a receiving molecule, a receptor. Receptors and ligands exist in many different forms, and only recognize/bond to particular molecules. Upstream extracellular signaling transduce a variety of intracellular cascades. [1]
Genes are transferred via transduction as the prophage genome is imperfectly excised from the host chromosome and integrated into a new host (specialized transduction) or as fragments of host DNA are packaged into the phage particles and introduced into a new host (generalized transduction). [2]
In the lytic pathway, viral replication proceeds immediately following infection and releases approximately 300–500 phage progeny via cell lysis within an hour. [1] However, in the lysogenic pathway, the phage chromosome integrates into the host chromosome and is passed to daughter cells through cell division. [ 1 ]
The signal transduction component labeled as "MAPK" in the pathway was originally called "ERK," so the pathway is called the MAPK/ERK pathway. The MAPK protein is an enzyme, a protein kinase that can attach phosphate to target proteins such as the transcription factor MYC and, thus, alter gene transcription and, ultimately, cell cycle progression.

In cell biology, there are a multitude of signalling pathways. Cell signalling is part of the molecular biology system that controls and coordinates the actions of cells.. Akt/PKB signalling pathway
