The correct sequence of substances that appeared during the course of origin of life on earth was

The initial atmosphere consisted of H,N,C and O. Hydrogen reacted with nitrogen to form ammonia, with carbon to form methane and with oxygen to form water vapour.

Proteins combined with nucleic acids to form nucleoproteins.
