Cytosine is to pyrimidine as guanine is to
WebJul 7, 2024 · In DNA, adenine always pairs with thyine and cytosine always pairs with guanine. These pairings occur because of geometry of the base,s allow hydrogen bonds to form only between the “right” pairs. Adenine and thymine will form two hydrogen bonds, whereas cytosine and guanine will form three hydrogen bonds. Webcytosine: [noun] a pyrimidine base C4H5N3O that codes genetic information in the polynucleotide chain of DNA or RNA — compare adenine, guanine, thymine, uracil.
