RNA tends to be single stranded so its bases do not pair very often.
During transcription, the mRNA does pair to the DNA for a short time producing a DNA hybrid. In this case complementary base pairing will occur- But you need to be careful however as RNA contains U bases instead of T.
RNA - DNA:
A- T
U- A
G-C
C-G
In some virus', the viral genome can also be double stranded RNA- quite rare!
so in this case- all the above except A will pair with U because T is not availible in RNA.

DNA to RNA Cytosine to Guanine Guanine to Cytosine Adenine to Uracil Thymine to Adenine
RNA uses uracil instead of thyminelike DNA does.

The turns are formed from complementary base pairing and cause separation of the RNA transcript and RNA polymerase.
Although the base pairing between two strands of DNA in a DNA molecule can be thousands to millions of base pairs long, base pairing in an RNA molecule is limited to short stretches of nucleotides in the same molecule or between two RNA molecules.
The Complementary base pairing of DNA is A with T and C with G. In Rna, T is replaced with U.
Th nitrogen bases for DNA are: thymine (T), guanine (G), cytosine (C) and adenine (A). For RNA they are adenine, guanine, cytosine and uracil (U).DNA base pairing is highly specific: T pairs with A (T-A) and G pairs with C (G-C).RNA base pairing is not as specific, but can be said to occur like so: U pairing with A (U-A) and G pairing with C.
dna : A=T C=G rna A=U C=G
The pairing of bases allows the cells to replicate.
There is no thymine in RNA, there is uracil instead. So in DNA the base pairs are adenine - thymine and cytosine-guanine, and in RNA adenine-uracil and cytosine-guanine.
