From the results reported here, the accelerating effect of 2HT and IMZ salts can be justified, taking into consideration: (1) the presence of nitrogenous bases in both types of salts, in the imidazolinium ring and after thermal degradation occurring in vulcanization in 2HT, and (2) the increased mobility of sulfur anionic species.

the features that describe the nitrogenous bases as categorical effects (complimentary pairs as the base pairs, similar pairs as pyrimidines and purines, chiral pairs as the right and left twist of the helix, polar pairs as the bonding arrangements), and
Each rung became known as a base pair, because it consisted of a pair of nitrogenous bases (nucleotides) attached end to end.
When the nitrogenous bases bind in the center of the helix, adenine tends to bind with thymine, whereas guanine tends to bind with cytosine.
Kossel had isolated the nitrogenous bases of nucleic acid (see 1885) but had not been able to go further.
