The function of chromosomes is to carry the genetic information from one cell generation to another. That DNA, which is the only permanent component of chromosome structure, is the sole genetic material has been shown by a variety of experiments, which will be discussed in Chemistry of the Gene 1.  Nucleic Acids and Their Structure. Also, the manner in which DNA stores the genetic information will be dealt elsewhere (The Genetic Code). The replication of chromosome depends on a very precise replication of DNA. Details of semi-conservative mode of replication of DNA will be discussed in detail in Chemistry of the Gene 2.  Synthesis, Modification and Repair of DNA.
