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.

A= U, G= C, T= A You can reverse it as well to find the codons

The pairings are:

* A RNA binds to T of DNA (by 2 hydrogen bonds).

* U of RNA binds to DNA (by 2 hydrogen bonds).

* G binds to C (by 3 hydrogen bonds) these two bases are present in DNA and RNA.

The hydrogen bonds between the bases of one nucleic acid strand and the bases of another strand maintain the 2 strands united (This is the definition of the pairing).

A purine always binds to a pyrimidine on the other strand (so their numbers are equal).
