Detailed explanation-1: -Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA.
Detailed explanation-2: -In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.
Detailed explanation-3: -Abstract. Chargaff’ s second parity rule (PR2) states that complementary nucleotides are met with almost equal frequencies in single stranded DNA. This is indeed the case for all bacterial and eukaryotic genomes studied, although the genomic patterns may differ among genomes in terms of local deviations.
Detailed explanation-4: -Definition. A unit of two bases in a molecule of DNA or RNA. In DNA, adenine always pairs with thymine (A-T), and guanine always pairs with cytosine (G-C). RNA is the same, except that adenine always pairs with uracil (A-U).
