The main goal of the article is to analyze the most frequent metaphors of DNA: DNA IS A CODE / LANGUAGE / BOOK. First the history of origin of those metaphors is discussed, then connections of the metaphor DNA IS A BOOK with biblical beliefs ('Book of Life' mentioned in the Bible). The next issue is the influence of the metaphor DNA IS A BOOK OF LIFE, widespread by media, on the consciousness of non-specialists. Some examples from the common language are quoted and the poem by Czeslaw Milosz An Alcoholic enters the Gates of Heaven is analyzed.
