Q. No.Which of the following statements is true?
(1) A British scientist created the conditions proposed by Oparin and Haldane in a closed flask with temperature of 800 degree Celsius in electric discharge along with gases methane, hydrogen, ammonia and water vapour and observed formation of amino acid.
(2) Some similar experimental setups were also prepared by other scientists and formation of sugar, nitrogenous bases, Pigments and Fats was recorded.
(3) The processes of chemical evolution were occurring elsewhere in space was concluded by the analysis of content of gaseous cloud.
(4) The first self replicating metabolic capsule of life arose 3 billion years back.
