A signal outside a cell triggers changes in the transcription and translation inside the cell through
A)post-translational editing.
B)signal transduction pathways.
C)protein activation.
D)protein breakdown.

Question

Quizplus · Accepted Answer

Signal transduction pathways are responsible for transmitting signals from outside the cell to the inside of the cell, ultimately leading to changes in gene expression. This process involves a series of biochemical reactions that activate transcription factors and modify the activity of other proteins involved in transcription and translation. Post-translational editing and protein breakdown are not directly involved in the transmission of signals or the regulation of gene expression. Protein activation may play a role in signal transduction, but it is too broad of a term to accurately describe the specific process involved in this question.
