Answer:

Nucleus

Explanation:

In eukaryotic cells, the nucleus is a membrane-bound structure that contains the genetic material, which is expressed in response to cell stimuli (i.e., environmental stimuli). This genetic material consists of genes that are expressed in response to cell signaling events. For example, the transcription factors that are found in the cytoplasm are activated after receiving a signal from receptors localized in the cell membrane, when these membrane receptors bind to specific signaling molecules. Subsequently, these transcription factors are translocated into the nucleus to interact with DNA promoter regions in order to activate the expression (transcription) of target genes capable of responding to an environmental stimulus.
