    During transcription in a eukaryotic cell, which statement correctly describes the movement of RNA polymerase along the DNA template strand and the direction of RNA strand elongation?

    • A) RNA polymerase reads the DNA template strand in the 3' to 5' direction and synthesizes the RNA transcript in the 5' to 3' direction.
    • B) RNA polymerase reads the DNA template strand in the 5' to 3' direction and synthesizes the RNA transcript in the 3' to 5' direction.
    • C) RNA polymerase reads the DNA coding strand in the 3' to 5' direction and synthesizes the RNA transcript in the 3' to 5' direction.
    • D) RNA polymerase reads both DNA strands simultaneously in the 5' to 3' direction to assemble a double-stranded RNA molecule.
