Cell amplification occurs through a process called signal transduction, where a single extracellular signal, such as a hormone or growth factor, binds to a receptor on the cell surface. This binding activates a cascade of intracellular signaling pathways, often involving secondary messengers that amplify the initial signal. As a result, a small number of signaling molecules can lead to a large cellular response, such as increased gene expression or cell division. This mechanism is crucial for processes like development, immune responses, and tissue repair.

What is the relationship between divergence and amplification?

Gene duplication (or chromosomal duplication or gene amplification) is any duplication of a region of DNA that contains a gene; it may occur as an error in homologous recombination, a retrotransposition event, or duplication of an entire chromosome.


How current amplification is occur in a transistor?

A: Vacuum tubes are current amplifiers transistors are voltage amplifier. The voltage drop across the collector resistor causes amplification since very little current in the base will change a large current in the collector.
