WebHydrogen bonding in DNA: DNA is made up of four bases Adenine (A), Cytosine (C), Guanine (G), and Thymine (T). With the assistance of hydrogen bonding, the reciprocal base pairing of Guanine to Cytosine and Adenine to Thymine are correlated. These hydrogen bonds are what keep together the two ends of the DNA helix between complementary nucleotides. WebJun 6, 2024 · A DNA molecule consists of two strands wound around each other, with each strand held together by bonds between the bases.
