Purines and Pyridines in the tail of a comet can

transform into organic matter containing C, H, O, N & S at high

temperatures

Adenine and Guanine combine together along with Cytosine and Thymine

combining together to form the Purines and Pyridines at high temperatures.

Some of the compounds in the tail of a comet can

transform to Purines and Pyridines at high temperatures

nucleotides present in the tail can transform into

the carbonaceous cell mass of the living organisms at high temperatures.
