Which of the Following Initiates the Process of Transcription

Question

Which of the following initiates the process of transcription?  
A) RNA polymerase
B) DNA polymerase
C) Helicase
D) Transfer RNA
E) Exons

Accepted Answer

Transcription is the process of making an RNA copy of a DNA sequence. This process is initiated by RNA polymerase, an enzyme that binds to a specific region of the DNA called the promoter. DNA polymerase is an enzyme that is involved in DNA replication. Helicase is an enzyme that unwinds the double-stranded DNA, while transfer RNA is involved in protein synthesis. Exons are the coding regions of DNA that are transcribed into RNA.
