Transcription of part of a DNA molecule with a nucleotide sequence of AAACAACTT results in a mRNA molecule with the complementary sequence of
A) GGGAGAACC.
B) UUUGUUGAA.
C) TTTGAAGCC.
D) CCCACCTCC.
E) AAACAACTT.

Question

Quizplus · Accepted Answer

During transcription, RNA polymerase reads the DNA template strand in the 3' to 5' direction and synthesizes a complementary RNA molecule in the 5' to 3' direction. The nucleotide sequence AAACAACTT in the DNA template strand would pair with the complementary sequence UUUGUUGAA in the RNA molecule. Therefore, the correct answer is B.
