Base Pairing in Transcription

Steps:

• RNA polymerase synthesizes mRNA complementary to the DNA template strand during transcription.
• Base pairing rules: RNA A pairs with DNA T; RNA U pairs with DNA A; RNA G with DNA C; RNA C with DNA G.
• Translation involves mRNA-tRNA pairing, not direct RNA-DNA pairing.
• Choices C and D are missing, making full evaluation impossible.

Why C is correct:

• Not enough information; choice C is blank and cannot be assessed.

Why the others are wrong:

• A: Incorrect process timing; RNA A pairs with DNA T in transcription, but choice specifies wrong context or detail unclear without full options.
• B: Translation does not involve RNA-DNA pairing; it uses codon-anticodon matching between mRNA and tRNA.

Final answer: C
