“They also knew that there was a string of DNA at the end of each chromosome called a telomere, which shortened a tiny bit each time a cell divided, like time ticking off a clock. As normal cells go through life, their telomeres shorten with each division until they’re almost gone. Then they stop dividing and begin to die. This process correlates with the age of a person: the older we are, the shorter our telomeres, and the fewer times our cells have left to divide before they die. By the early nineties, a scientist at Yale had used HeLa to discover that human cancer cells contain an enzyme called telomerase that rebuilds their telomeres. The presence of telomerase meant cells could keep regenerating their telomeres indefinitely. This explained the mechanics of HeLa’s immortality: telomerase constantly rewound the ticking clock at the end of Henrietta’s chromosomes so they never grew old and never died.”

“If you think about brewing, it is biotechnology. And I would say that I was a technologist at heart. So whether I... fermented beer or whether I fermented enzymes, the base technology was the same.”
Kiran Mazumdar-Shaw“What I found out on Christmas Day 1984, through biochemical evidence, was that telomeres could be lengthened by the enzyme we called telomerase, which keeps the telomeres from wearing down. After I found that out, I went home and put on Bruce Springsteen's 'Born in the USA,' which was just out, and I danced and danced and danced.”
Carol W. Greider“There's a great metaphor that one of my doctors uses: If a fish is swimming in a dirty tank and it gets sick, do you take it to the vet and amputate the fin? No, you clean the water. So, I cleaned up my system. By eating organic raw greens, nuts and healthy fats, I am flooding my body with enzymes, vitamins and oxygen.”
Kris Carr“The uniformity of the earth's life, more astonishing than its diversity, is accountable by the high probability that we derived, originally, from some single cell, fertilized in a bolt of lightning as the earth cooled. It is from the progeny of this parent cell that we take our looks; we still share genes around, and the resemblance of the enzymes of grasses to those of whales is a family resemblance.”
Lewis Thomas, The Lives of a Cell: Notes of a Biology Watcher“Humans! They lived in a world where the grass continued to be green and the sun rose every day and flowers regularly turned into fruit, and what impressed them? Weeping statues. And wine made out of water! A mere quantum-mechanistic tunnel effect, that'd happen anyway if you were prepared to wait zillions of years. As if the turning of sunlight into wine, by means of vines and grapes and time and enzymes, wasn't a thousand times more impressive and happened all the time...”
Terry Pratchett, Small Gods“Few scientists acquainted with the chemistry of biological systems at the molecular level can avoid being inspired. Evolution has produced chemical compounds exquisitely organized to accomplish the most complicated and delicate of tasks. Many organic chemists viewing crystal structures of enzyme systems or nucleic acids and knowing the marvels of specificity of the immune systems must dream of designing and synthesizing simpler organic compounds that imitate working features of these naturally occurring compounds.”
