Question

which nitrogenous base provides additional stability to dna

Answer 1

Thus, in DNA, the purines adenine (A) and guanine (G) pair up with the pyrimidines thymine (T) and cytosine (C), respectively. In RNA, the complement of adenine (A) is uracil (U) instead of thymine (T), so the pairs that form are adenine:uracil and guanine:cytosine.

Chemical formula: C4H4N2

Solubility in water: Miscible (25°C)

Boiling point: 123 to 124 °C (253 to 255 °F; 396 to 397 K)

Melting point: 20 to 22 °C (68 to 72 °F; 293 to 295 K)
