Verified step by step guidance1
Understand the process of transcription: Transcription is the synthesis of RNA from a DNA template, where the DNA sequence is copied into RNA.
Identify the role of RNA polymerase: RNA polymerase is the enzyme responsible for reading the DNA template and synthesizing the RNA strand.
Determine the direction of RNA synthesis: RNA polymerase synthesizes RNA in the 5' to 3' direction, meaning it adds nucleotides to the 3' end of the growing RNA strand.
Clarify the movement of RNA polymerase along the DNA: To synthesize RNA in the 5' to 3' direction, RNA polymerase must move along the DNA template strand in the 3' to 5' direction.
Conclude the direction of RNA polymerase movement: RNA polymerase moves along the DNA template strand in the 3' to 5' direction during transcription.
