FAQs

Question: What is the main function of transcription in cells?
Answer: Transcription is the process of copying a segment of DNA into RNA, which is essential for protein synthesis.

Question: How do transcription factors influence gene expression?
Answer: Transcription factors bind to specific DNA sequences, promoting or inhibiting the transcription of genes, thus regulating gene expression.
