Which of the following is the main component of ribosomes, where polypeptide chains are built?
Ribosomal RNA (rRNA)
What is the role of the promoter region in transcription?
It is where RNA polymerase binds to initiate transcription.
What is the role of the template strand during transcription?
It is the strand that is used to synthesize mRNA.
