Understand that during transcription, RNA is synthesized from a DNA template strand by complementary base pairing.
Recall the base pairing rules between DNA and RNA: Adenine (A) in DNA pairs with Uracil (U) in RNA, and Thymine (T) in DNA pairs with Adenine (A) in RNA.
Recognize that Uracil (U) is unique to RNA and replaces Thymine (T) found in DNA.
Identify that Uracil (U) in RNA pairs specifically with Adenine (A) in the DNA template strand during transcription.
Conclude that the correct DNA base pairing with Uracil (U) in RNA is Adenine (A).
