What: "DNA is like a book which is made up out of four letters: Adenine, Guanine, Cytosine, and Thymine (A C G T) that appear in a certain sequence.One chromosome is like a sentence, much of it doesn't make any sense to us: the letters seem to be in a random order. But sometimes the letter DO make sense, that is a gene, like a word."
