Answer:
The correct answer is nitrogen bases of RNA are never hydrogen bonded to other bases.
Explanation:
The nitrogen bases present in RNA are Adenine guanine cytosine and uracil.Adenine pairs with uracil whereas guanine pairs with cytosine by 3 hydrogen bonds.
The base pairing between codon of mRNA and anticodon of tRNA can be seen during translation elongation.
The base pairing is also seen during the formation of hairpin structure during rho independent termination of transcription.
