Answer:
The correct answer is option d) "Silencer".
Explanation:
Gene silencing is the regulation of a gene expression that results in avoiding the expression of a gene during a certain period of time. A silencer is a DNA sequence that produces gene silencing. In this example the researcher founds that a gene is not longer regulated in all cells and the gene is still transcribed and translated into protein. The mutation responsible of this it is likely to be occurring in a silencer, avoiding gene silencing of the studied gene in all cells.
The answer is C. An effector is analogous to the way a ligand (of a stimuli) binds to receptors on the surface of the body and triggers an impulse in the neuron. An effector, on the other hand, occurs internally of the body and when the effector molecule binds to the receptors of the organ that it stimulates or suppresses, a cascade signaling pathway in the cells occurs and the cells/organs responds requisitely.
