  • Classification Of Viruses
    795 words
    Viruses: Complex Molecules or Simple Life Forms? Viruses have been defined as 'entities whose genomes are elements of nucleic acid that replicate inside living cells using the cellular synthetic machinery, and cause the synthesis of specialised elements that can transfer the genome to other cells.

  • Different Organic Compounds And Many Amino Acids

    Alexander Oparin and J.B.S. Haldane developed a theory of Biogenesis between the years of 1922 and 1928. With Oparin's "The Origin of Life" and Haldane's technical papers they created concrete hypothetical models from their knowledge of physics and biochemistry. Their only obstacle was practical proof to base their discoveries upon. Oparin speculated that Earth, in its early stages, had several different reactions occurring caused by nature. Organic compounds formed out of inorganic material tha...

  • Living Organisms In The Biosphere
