Which of the Following is True of Transcription Factors

Question

Which of the following is true of transcription factors?
A) They regulate the synthesis of DNA in response to a signal.
B) They transcribe ATP into cAMP.
C) They initiate the epinephrine response in animal cells.
D) They control gene expression.
E) They regulate the synthesis of lipids in the cytoplasm.

Accepted Answer

Transcription factors are proteins that bind to DNA and control the expression of genes, which involves the process of transcription. They do not regulate the synthesis of DNA or lipids, nor do they transcribe ATP into cAMP or initiate the epinephrine response in animal cells.
