PPT-MCB- Signal Transduction Lecture 1

General Concepts of Signal Transduction Cell Communication Types of Receptors Molecular Signaling Receptor Binding Scatchard Analysis Competitive Binding Second Messengers Signaling throughout Evolution. Many factors can affect transduction efficiency. Not all viral particles floating in culture medium can eventually transduce (or infect) the cells. Some additives such as polybrene can enhance the t DR AMINA TARIQ. BIOCHEMISTRY. Survival of a multicellular organism depends on their ability to adapt to the constantly changing environment.. Intercellular communication mechanisms are necessary for this adaptation.. Chapter 13, . Stryer. Short Course. Signal Transduction. Signal from exterior of cell must affect interior of cell.
