Definitions:

Promoters

DNA sequences located upstream of a gene that initiate transcription by binding RNA polymerase and other necessary transcription factors.

Silencers

DNA sequences that can bind regulatory proteins to inhibit the expression of a gene, thus playing a crucial role in gene regulation.

Upstream Promoter Elements

Regions of DNA located before (upstream of) the coding sequence of a gene that help initiate transcription by providing binding sites for RNA polymerase and transcription factors.

Eukaryotes

Organisms whose cells have a nucleus enclosed within a nuclear envelope, making up one of the three recognized domains of life, including plants, animals, fungi, and protists.
