what makes the DNA a good information bearing molecule?
DNA is an information bearing molecule  a language molecule. It is constructed out of very long chains of four different small composite molecules, and the order of these four molecules determines the message coded into the molecule, just as the order of letters in a word determines the meaning of the word.he process by which the instructions in a DNA molecule are read and followed is one of the most amazing phenomena of life. It involves a third kind of molecule called RNA, and the activity of the cell's army of ribosomes.
