A signal outside a cell triggers changes in the transcription and translation inside the cell through

Question

Quizplus · Accepted Answer

Signal transduction pathways are the series of molecular events that transmit signals from the outside of the cell to the inside, leading to changes in gene expression and protein synthesis. This process involves the activation of cell surface receptors, the transmission of the signal to downstream molecules, and ultimately the activation of transcription factors that bind to DNA and regulate gene expression. Hence, option B is the best choice. The other options (protein breakdown, post-translational editing, and protein activation) are not directly involved in the signal-transduction process.
