MCQs:  The hard Liithosphere was studded with volcanic eruptions pouring out hot lava. The Nitrogen and Carbon Atoms of atmosphere formed nitrides and Carbides respectively by reacting with metallic atoms of lava. The hot water vapours of atmosphere and carbides reacted to form Methane and water vapours and metallic nitrides reacted to form Ammonia.

MCQs:  During the course of time of origin of life, the nucleic acids were formed in the primitive ocean. Certain proteins like histones associated with these nucleic acids to form nucleoproteins which appeared as "Self-duplicating System" by virtue of this property the nucleic acid became capable of performing hereditary function.

MCQs:  According to Horowitz (1945) and Leslie Orgel (1975) the life originated in the sea as free naked gene which linked into chains and later proteins gathered around them to form viruses. The viruses by gathering other molecules and forming a thin binding membrane organized into prokaryotes. Whether this statements is:
