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. None of theseB. FalseC. Partially wrong D. True Loading... 2. 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. EthanolB. Methane C. Carbon-dioxide D. Ethane Loading... 3. Karyon is the basis of differentiation in between?A. Enaima and Anaima B. None of theseC. Prokaryotes and EukaryotesD. Protista and Monera Loading... 4. True Nucleus is absent in bacteria because?A. The nuclear membrane is absent B. None of theseC. The histones do not form complex with DNA D. Bacteria lack nuclear membrane and histones Loading... 5. 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. Oparin C. AristotleD. Lamarck Loading... 6. 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.
