Document Summary

Progeny: a descendant or the descendants of a person, animal, or plant; offspring. Heredity: the passing on of physical or mental characteristics genetically from one generation to another. Most living organisms are single cells; others, such as ourselves, are vast multicellular cities in which groups of cells perform specialized functions and are linked by intricate systems of communication. The whole organism has been generated by cell divisions from a single cell. Complex: assembly of molecules that are held together by non-covalent bonds. All cells store their hereditary information in the same linear chemical code (dna) Living cells, like computers, deal in information, and it is estimated that they have been evolving and diversifying for over 3. 5 billion years. All living cells on earth, without any known exception, store their hereditary information in the form of double-stranded molecules of dna long unbranched paired polymer chains, formed always of the same four types of monomers a, t, c, g.
