Answer to Question #35767 in Molecular Biology for kanchan

Question

explain the process of signalling mediated by intracellular receptors.

Answer 1

The signal molecule enters the cell and combines with receptors inside the cell. Those receptors are usually transcription factors in the inactive form. When they combine with the signal molecule, they become activated and move to the nucleus. There they affect the process of transcription, resulting in the expression of some genes and repression of the others.
