Transcription factor-DNA, molecular model. Strand of DNA (deoxyribonucleic acid, blue) being acted on by a transcription factor (orange and green). Transcription factors are proteins that are part of the process by which the information contained in DNA is used to make proteins. This is the NF-kB transcription factor, which mediates the response to inflammation.
