    Transmission of generational characteristics stored in DNA regulatory molecules ?

    DNA may not be alone in containing the information necessary for the transmission of generational characteristics. The majority of instructions would be much more complicated and stored in DNA regulatory molecules.

     

     

    Spatial arrangement affects the various chemical reactions in cells

    A computational model of human cell reveals the effect of spatial organization within cells. Simulations changed a process named RNA splicing that changes the messenger RNA molecules that carry information needed from DNA to form proteins. Spatial arrangement affects the various chemical reactions in cells.
