Genome They are the volums of an encyclopaedia called Genome. Cell Nucleus Tissues The chromosomes contains the instruction of alive beings

Dna STRUCTURE 1953 – Watson and Crick discover the structure of DNA 1953 – Rosalind Franklin X difraction image of DNA But what are the letters, the words and the sentences?
3
Chromosomes: the letters The a chromosome will be:... A T A G G C T A C G C A A A C C G G T C T A... Two strands of DNA: alphabet of four bases { A, C, G, T} complementaries (A T, G C) Base … and the words and sentences?
