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. This statement regarding origin and evolution of organic compounds is: (A) Correct (B) Partially wrong (C) Wrong (D) None of these
Amino acids, Sugards, Glycerol, Fatty acids, Nitrogen bases etc. formed in the primitive ocean survived because they were neither oxidized nor putrified. The reason were: (A) Absence of oxygen in primitive ocean (B) Absence of Bacteria in the environment (C) Both (a) and (b) (D) None of these
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. The statement according to your opinion is: (A) TRUE (B) Wrong (C) Partially wrong (D) None of these
The coaservates which acquired nucleoproteins became first cellular organisms and their parts later became modified during the course of time due to chemical changes in the nucleic acid is the view of the scientist: (A) Oparin (B) Lamarck (C) Darwin (D) Aristotle
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: (A) Correct (B) Incorrect (C) Partially incorrect (D) Absurd
True Nucleus is absent in bacteria because: (A) The nuclear membrane is absent (B) The histones do not form complex with DNA (C) Bacteria lack nuclear membrane and histones (D) None of these
