The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G)

Does RNA have complementary base pairing? noun Genetics.either of the nucleotide bases linked by a hydrogen bond on opposite strands of DNA or double-stranded RNA: guanine is the complementary base of cytosine, and adenine is the complementary base of thymine in DNA and of uracil in RNA.

What does thymine pair with in RNA? In RNA the base Thymine is not present, instead the base Uracil is present which has a very similar structure to Thymine. As aresult Adenine pairs with Uracil (A-U) via the same hydrogen bonding interactions as in the A-T base pair.

What are the 3 types of RNA? Three major types of RNA are mRNA, or messenger RNA, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA, that serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to theribosome to be assembled
