Title: Quick identifications of the nitrogenous bases
Post by: kenhung123 on June 01, 2010, 11:23:10 pm

Ok sometimes its annoying to look at a question that requires you to identify which base in the data book is required. Is there anything that is characteristic of each particular nitrogenous base?

CG = 3 h bonds.

Adenine has no carbonol group and no oxygen whatsoever.

You know about purines and pyramidines im sure.

Right, that is useful, by any chance is there anything to distinguish Cytoseine and thymine quickly?
