Trans-Acting Proteins That Influence Transcription are Generally Referred to As

Question

Trans-acting proteins that influence transcription are generally referred to as
A)DNA polymerases.
B)tumor suppressors.
C)enhancers.
D)transcription factors.
E)promoters.

Accepted Answer

Transcription factors are proteins that bind to specific DNA sequences, thereby controlling the flow (or transcription) of genetic information from DNA to mRNA. They are considered trans-acting because they can regulate the transcription of genes located elsewhere on the DNA molecule, not just adjacent to them.
