Read the following statements regarding transcription: (A) The DNA strand with 3^ 5^ polarity acts as the template for RNA polymerase. (B) The sequence of the coding strand is the same as the newly synthesized mRNA except that thymine is present in place of uracil. (C) DNA-dependent RNA polymerase catalyzes polymerization in the 3^ 5^ direction. (D) If the sequence of the coding strand is 5^ -ATC- 3^ , the mRNA produ

Step-by-step solution

Statement (A) is correct: RNA polymerase catalyzes polymerization in the 5^ 3^ direction, so the template strand must have 3^ 5^ polarity. Statement (B) is correct: The coding strand has the same sequence and 5^ 3^ polarity as the transcribed mRNA, with thymine (T) instead of uracil (U). Statement (C) is incorrect: DNA-dependent RNA polymerase catalyzes polymerization only in one direction, that is, 5^ 3^ . Statement (D) is incorrect: The mRNA sequence is identical to the coding strand (with U replacing T). If the
