Definitions:

Eukaryotic Transcription Factors

Proteins in eukaryotic cells that bind to DNA sequences to regulate the transcription of genetic information from DNA to messenger RNA.

CAPs

Cyclic AMP Receptor Proteins, which are involved in the regulation of gene expression in response to fluctuations in cellular levels of cyclic AMP.

Activators

Proteins that bind to DNA and increase the rate of transcription, playing a crucial role in gene regulation.

Repressors

Proteins that bind to specific DNA sequences and inhibit the transcription of genes, playing a crucial role in gene regulation.
