There are five types of nucleotides in nature which are the building blocks of RNA and DNA and these are the same in all living organisms . These nucleotides are Adenine, Thymine, Guanine, Cytosine and Uracil.
According to base pairing rules, in all DNA molecules Adenine will always pair with Thymine while Guanine will always pair with Cytosine.
This rule is the same with RNA except that here Thymine is replaced with Uracil. Otherwise the base pairing rule applies in all living organisms, that is to say it is universal.
