WebSep 14, 2024 · Adenine pairs with uracil in RNA molecules (e.g., when the rRNA codons pair with tRNA anti-codons in translation or when DNA is transcribed into RNA). Adenine must … WebRNA Polymerases use a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand. While base pairing, adenine (A) always pairs with thymine (T) in the case of DNA while it pairs with uracil (U) in ...
