Today we are going to come up with new task, that is about ”Which of the following is true of transcription factors?“. We have found the solution to this question, along with interesting information related to it, thanks to its novelty and interest.  This is where we will focus to gain this useful and new knowledge!

Question: “Which of the following is true of transcription factors?”

Which of the following is true about transcription factors? a. They regulate the synthesis of DNA in response to a signal. b. They are needed to regulate the synthesis of a protein in the cytoplasm. c. They control which genes are turned on to form mRNA. d. They block the mRNA from being translated.

Answer: “Which of the following is true of transcription factors?”

They control which genes are turned on to form mRNA. Transcription factors are proteins that regulate the transcription of genes – their copying into RNA, on the way to making a protein. They do not block mRNA from being translated, or regulate the synthesis of DNA in response to a signal, and are not needed to regulate the synthesis of a protein in cytoplasm.

Relevant knowledge

Transcription factors are proteins that bind to DNA and either promote or block gene expression. The key mechanism for gene regulation is activation and inhibition transcription factors.
