201. “Without equality, he argued, eugenics would degenerate into yet another mechanism by which the powerful could control the weak.”

— Siddhartha Mukherjee

202. “Neither variant was morally or biologically superior; each was just more or less adapted to a particular environment.”

— Siddhartha Mukherjee

203. “Every genetic “illness” is a mismatch between an organism’s genome and its environment.”

— Siddhartha Mukherjee

204. “Three profoundly destabilizing scientific ideas ricochet through the twentieth century, trisecting it into three unequal parts: the atom, the byte, the gene. Each is foreshadowed by an earlier century, but dazzles into full prominence in the twentieth. Each begins its life as a rather abstract scientific concept, but grows to invade multiple human discourses – thereby transforming culture, society, politics, and language.”

— Siddhartha Mukherjee

205. “It is the impulse of science to try to understand nature, and the impulse of technology to try to manipulate it. Recombinant DNA had pushed genetics from the realm of science into the realm of technology.”

— Siddhartha Mukherjee

206. “Without this variation – without deep genetic diversity – an organism might ultimately lose its capacity to evolve.”

— Siddhartha Mukherjee

207. “Junk science props up totalitarian regimes. And totalitarian regimes produce junk science.”

— Siddhartha Mukherjee

208. “They were self-appointed jesters in a court of fools. The.”

— Siddhartha Mukherjee

209. “Life’s definition, as it stands now, is akin to a menu. It is not one thing but a series of things, a set of behaviors, a series of processes, not a single property. To be living, an organism must have the capacity to reproduce, to grow, to metabolize, to adapt to stimuli, and to maintain its internal milieu.”

— Siddhartha Mukherjee

210. “I had a novice’s hunger for history, but also a novice’s inability to envision it.”

— Siddhartha Mukherjee

211. “If you prefer an “academic life” as a retreat from reality, do not go into biology. This field is for a man or woman who wishes to get even closer to life. – Hermann Muller We.”

— Siddhartha Mukherjee

212. “More than the enormity of gene numbers, the diversity of gene types, or the originality of gene function, it is the ingenuity of our genome that is the secret to our complexity.”

— Siddhartha Mukherjee

213. “The capacity to organise information or to perform goal-oriented tasks collapsed, and new words, fears, and anxieties emerged, as if from the netherworlds of the mind. In the end, all organized thinking began to crumble, entrapping the schizophrenic within a maze of mental rubble.”

— Siddhartha Mukherjee

214. “Eugenicists such as Priddy had long worried that the flooding of America by immigrants would precipitate “race suicide.” The right people were being overrun by the wrong people, they argued, and the right genes corrupted by the wrong ones. If.”

— Siddhartha Mukherjee

215. “There was, perhaps, no more bizarre illustration of the conflation between cleansing and racial cleansing than a law that barred Jews from employing “German maids” in their houses.”

— Siddhartha Mukherjee

216. “It is here that an insight enters our discussion – and it might sound peculiar at first: a test can only be interpreted sanely in the context of prior probabilities.”

— Siddhartha Mukherjee

217. “Illness is used to define wellness. Abnormalcy marks the boundaries of normalcy. Deviance demarcates the limits of conformity.”

— Siddhartha Mukherjee

218. “To see,” the poet Paul Valery once wrote, “is to forget the name of the things that one sees.” To see DNA is to forget its name or its chemical formula. Like the simplest of human tools-hammer, scythe, bellows, ladder, scissors-the function of the molecule can be entirely comprehended from its structure. To “see” DNA is to immediately perceive its function as a repository of information. The most important molecule in biology needs no name to be understood.”

— Siddhartha Mukherjee

219. “Units of hereditary information, encoded in DNA and packaged on chromosomes, are transmitted through sperm and egg into an embryo, and from the embryo to every living cell in an organism’s body.”

— Siddhartha Mukherjee

220. “The word genocide shares its root with gene – and for good reason: the Nazis used the vocabulary of genes and genetics to launch, justify, and sustain their agenda.”

— Siddhartha Mukherjee

221. “We lost a chromosome, but gained a thumb.”

— Siddhartha Mukherjee

222. “The experiments progress slowly,” Mendel wrote. “At first a certain amount of patience was needed, but I soon found that matters went better when I was conducting several experiments simultaneously.” With multiple crosses in parallel, the production of data accelerated. Gradually, he began to discern patterns in the data-unanticipated constancies, conserved ratios, numerical rhythms. He had tapped, at last, into heredity’s inner logic.”

— Siddhartha Mukherjee

223. “Indeed, the mean height of the sons of exceptionally tall fathers tended to be slightly lower than the father’s height-and closer to the population’s average-as if an invisible force were always dragging extreme features toward the center. This discovery-called regression to the mean-would have a powerful effect on the science measurement and the concept of variance. It would be Galton’s most important contribution to statistics.”

— Siddhartha Mukherjee

224. “Why, you might ask, do the medical mysteries of the Covid-19 pandemic sit at the center of a book on cell biology? Because cell biology sits at the center of the medical mysteries.”

— Siddhartha Mukherjee

225. “The double-helix has solved all three of the major challenges of genetic physiology using ingenious variations on the same theme. Mirror-image chemicals are used to generate mirror-image chemicals, reflections used to reconstruct the orginal. Pairs used to maintain the fidelity and fixity of information. “Monet is but an eye,” Cezanne once said of his friend, “but, God, what an eye.” DNA, by the same logic, is but a chemical-but, God, what a chemical.”

— Siddhartha Mukherjee

226. “The tightness of genetic linkage, in short, was a surrogate for the physical proximity of genes on chromosomes: by measuring how often two features-blond-hairedness and blue-eyedness-were linked or unlinked, you could measure the distance between their genes on the chromosome.”

— Siddhartha Mukherjee

227. “It sometimes seems as if curbing entropy is our quixotic purpose in the universe,” James Gleick wrote.”

— Siddhartha Mukherjee

228. “Dimly, as if through a veil, geneticists were beginning to visualize patterns and themes: threads, strings, maps, crossings, broken and unbroken lines, chromosomes that carried information in a coded and compressed form. But no one had seen a gene in action or knew its material essence. The central quest of the study of heredity seemed like an object perceived only through its shadows, tantalizingly invisible to science.”

— Siddhartha Mukherjee

229. “In 1962, Watson, Crick, and Wilkins won the Nobel Prize for their discovery. Franklin was not included in the prize. She had died in 1958, at the age of thirty-seven, from diffusely metastatic ovarian cancer-an illness ultimately linked to mutations in genes.”

— Siddhartha Mukherjee

230. “The most extreme novelty seekers-the greatest among the Gatsbys-seemed virtually addicted to stimulation and excitement. Scores aside, even their test-taking behavior was temperamental. They left questions unanswered. They paced the room, trying to look for ways to get out. They were frequently, hopelessly, maddeningly bored.”

— Siddhartha Mukherjee

231. “With DNA as with words, the sequence carries the meaning. Dissolve DNA into its constituent bases, and it turns into a primordial four-letter alphabet soup.”

— Siddhartha Mukherjee

232. “In 1905, still struggling for an alternative, Bateson coined a word of his own. Genetics, he called it: the study of heredity and variation-the word ultimately derived from the Greek genno, “to give birth.”

— Siddhartha Mukherjee

233. “When a virus enters a cell, it sheds its coat, and begins to use the cell as a factory to copy its genes, and manufacture new coats, resulting in millions of new viruses budding out of the cell. Viruses have thus distilled their life cycle to its bare essentials. They live to infect and reproduce; they infect and reproduce to live.”

— Siddhartha Mukherjee

234. “Six decades and two years, no more than a passing glance of time, separate Mendel’s initial experiments on peas and the court-mandated sterilization of Carrie Buck. Yet in this brief flash of six decades, the gene had transformed from an abstract concept in a botanical experiment to a powerful instrument of social control.”

— Siddhartha Mukherjee

235. “Darwin read the study, but he was not particularly convinced, damning his cousin with faint praise: “You have made a convert of an opponent in one sense, for I have always maintained that, excepting fools, men did not differ much in intellect, only in zeal and hard work.”

— Siddhartha Mukherjee

236. “We seek constancy in heredity – and find its opposite: variation. Mutants are necessary to maintain the essence of our selves. Our.”

— Siddhartha Mukherjee

237. “But it is more illuminating to write the history of technology through transitions: linear motion to circular motion; visual space to subvisual space; motion on land to motion in air; physical connectivity to virtual connectivity.”

— Siddhartha Mukherjee

238. “The controlled binding and unbinding of iron and oxygen- the cyclical rusting and unrusting of blood-allows effective oxygen delivery into tissues. Hemoglobin allows blood to carry seventyfold more oxygen than what could be dissolved in liquid blood alone.”

— Siddhartha Mukherjee

239. “The mother and the father were two independent sides and the child was the third – the biological hypotenuse to the parents’ two lines.”

— Siddhartha Mukherjee

240. “Like musicians, like mathematicians – like elite athletes – scientists peak early and dwindle fast.”

— Siddhartha Mukherjee

241. “What if the solution to the structure of DNA could be achieved by the same “tricks” that Pauling had pulled? X-ray pictures would help, of course – but trying to determine structures of biological molecules using experimental methods, Crick argued, was absurdly laborious – “like trying to determine the structure of a piano by listening to the sound it made while being dropped down a flight of stairs.”

— Siddhartha Mukherjee

242. “There is no history; there is only biography,” Emerson once wrote.”

— Siddhartha Mukherjee

243. “Incomplete penetrance” meant that even if a mutation was present in the genome, its capacity to penetrate into a physical or morphological feature was not always complete.”

— Siddhartha Mukherjee

244. “Never before in history, and never with such insidiousness, had genes been so effortlessly conflated with identity, identity with defectiveness, and defectiveness with extermination.”

— Siddhartha Mukherjee

245. “But while Darwin’s encounters with the “natives” of South America in the 1830s had strengthened his belief in the common ancestry of humans, Galton only saw difference: “I saw enough of savage races to give me material to think about all the rest of my life.”

— Siddhartha Mukherjee

246. “An upright organism with opposable thumbs is thus built from a script, but built to go off script. We call one such unique variant of one such organism a “self.”

— Siddhartha Mukherjee

247. “We had seen the mutants – and they were us.”

— Siddhartha Mukherjee

248. “It accommodates enough variation to make each one of us distinct, yet enough consistency to make each member of our species profoundly different from chimpanzees and bonobos, whose genomes are 96 percent identical to ours.”

— Siddhartha Mukherjee

249. “A gene,” Beadle wrote in 1945, “can be visualized as directing the final configuration of a protein molecule.” This was the “action of the gene” that a generation of biologists had been trying to comprehend: a gene “acts” by encoding information to build a protein, and the protein actualizes the form or function of the organism.”

— Siddhartha Mukherjee

250. “We loved them – and, yes, we killed them.”

— Siddhartha Mukherjee
