Transcription factors function in the expression of genes by

Question

Quizplus · Accepted Answer

Transcription factors are proteins that bind to specific sequences of DNA and control the transcription of genes. They can either activate (turn on) or repress (turn off) the expression of specific genes. Transcription factors can recruit RNA polymerase to the promoter region of a gene to initiate transcription or interfere with the binding of RNA polymerase, leading to the suppression of gene expression. Therefore, the correct answer is C, turning transcription of specific genes on or off.
