Answer:
Transcription of gene A is not affected
Explanation:
A transcriptional repressor is a DNA/RNA-binding protein that acts to suppress gene expression and/or protein synthesis by binding to target sequences. Moreover, a silencer is a DNA region that binds to particular transcriptional repressors in order to suppress gene expression. In this case, the transcriptional repressor is activated by binding to an effector molecule X (e.g., another protein). In consequence, and since the activated repressor-X complex is not more able to bind the silencer of gene A, it is expected that such complex will not be able to affect transcription of the target gene.
Answer:
Action potential.
Explanation:
Action potential may be defined as the change of the membrane potential of the cell with response to the stimulus. The different ions enter and exit the cells.
Action potential generates in the cell when the threshold voltage - gated channel reaches and opens the voltage gate channel. The opening of voltage gated channel changes the membrane potential of the cell.
Thus, the correct answer is option (4).
