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:
False
Explanation:
It does not have to touch it in order to have a effect on it.
The activation energy of a chemical reaction is closely related to its rate. Specifically, the higher the activation energy, the slower the chemical reaction will be. This is because molecules can only complete the reaction once they have reached the top of the activation energy barrier.
