“Genes are biochemical recipes written in a four-letter alphabet called DNA.”

“A four-letter alphabet called DNA.”

“What is truly revolutionary about molecular biology in the post-Watson-Crick era is that it has become digital...the machine code of the genes is uncannily computer-like.' -Richard Dawkins”

“The genome is a book that wrote itself, continually adding, deleting and amending over four billion years.”

“É claro que não há um único gene, mas há algo infinitamente mais enaltecedor e magnífico: toda uma naturza humana, flexivelmente pré-ordenada em nossos cromossomos e indiossincrática de cada um de nós. Todo mundo tem uma única e distina natureza endógena. Um self.”

“If, as a professor, you ask four men and two women each to wear a cotton T-shirt, no deodorant and no perfume, for two nights, then hand these T-shirts to you, you will probably be humored as a mite kinky.”

“The gene contains a single 'word', repeated over and over again: CAG, CAG, CAG, CAG ... The repetition continues sometimes just six times, sometimes thirty, sometimes more than a hundred times. Your destiny, your sanity and your life hang by the thread of this repetition. If the 'word' is repeated thirty-five times or fewer, you will be fine.Most of us have about ten to fifteen repeats. If the 'word' is repeated thirty-nine times or more, you will in mid-life slowly start to lose your balance, grow steadily more incapable of looking after yourself and die prematurely.”
