In this illustration, DNA is unzipping to make mRNA during transcription. DNA acts as a blueprint, pairing bases to make single strands of RNA. Identify the pairings you would see when DNA makes RNA.
The base pairings that would be observed when DNA is used for the synthesis of mRNA would be Adenine base paired or hydrogen bonded with Uracil while Guanine and Cytosine still hydrogen respectively with each other.
