To prove that organic molecules formed in the primitive ocean were respobsible for origin of life on earth, Millar carried out their synthesis from?A. NH3, H2, CH4, water vapourB. CH4, NH3, H2 C. CH4, N2, H2 D. NH3, H2, Water vapours Loading... 2. 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. Darwin B. Lamarck C. Oparin D. Aristotle Loading... 3. According to most accepted theories, the atmosphere of earth before origin of life consisted of a mixture of?A. Water vapours, Hydrogen, Ammonia and Methaine B. Ozone, Methane, Oxygen and WaterC. Hydrogen, Carbon Dioxide, Ammonia and Methane D. Oxygen, Ammonia, Methane and Water Loading... 4. 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 Bacteria in the environment B. None of theseC. Both (a) and (b) D. Absence of oxygen in primitive ocean Loading... 5. Stanley Miller in his classical experiment on formation of amino acids passed an electric discharge in the mixture of?A. Methane, Hydrogen, Nitrogen and steamB. Ammonia, Oxygen, Hydrogen and Water C. Methane, Carbondioxide, Oxygen and Hydrogen D. Steam, Methane, Hydrogen and Ammonia Loading... 6. In his experiment Stanley Miller was successful to demonstrate the formation of amino acids by passing an electric discharge in a mixture of ammonia, water, hydrogen and?A. Ethane B. EthanolC. Methane D. Carbon-dioxide Loading... 7. True Nucleus is absent in bacteria because?A. The nuclear membrane is absent B. The histones do not form complex with DNA C. None of theseD. Bacteria lack nuclear membrane and histones Loading... 8. 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.
