  1. 1.

    During transcription in living cells, which statement correctly describes the directional activity of RNA polymerase along the DNA molecule?

    • A) It moves along the template strand in the 3' to 5' direction while synthesizing RNA in the 5' to 3' direction.
    • B) It moves along the template strand in the 5' to 3' direction while synthesizing RNA in the 3' to 5' direction.
    • C) It reads both DNA strands simultaneously in the 5' to 3' direction to produce a double-stranded transcript.
    • D) It requires an RNA primer to initiate continuous synthesis from the 3' end to the 5' end of the new transcript.
