Cell mutation Quotes

“The extracellular genesis of cells in animals seemed to me, ever since the publication of the cell theory [of Schwann], just as unlikely as the spontaneous generation of organisms. These doubts produced my observations on the multiplication of blood cells by division in bird and mammalian embryos and on the division of muscle bundles in frog larvae. Since then I have continued these observations in frog larvae, where it is possible to follow the history of tissues back to segmentation.”

“We are but cells living in a much larger organism, however, this does not make our existence less significant – for an organism without cells is no organism at all. We define it; we make it what it is. We are responsible for its health, its functionality, and above all, its purpose. A lone cell can restore the others, or a lone cell can spread a plague.”

“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.”

“The ancestors of the higher animals must be regarded as one-celled beings, similar to the Amoebae which at the present day occur in our rivers, pools, and lakes. The incontrovertible fact that each human individual develops from an egg, which, in common with those of all animals, is a simple cell, most clearly proves that the most remote ancestors of man were primordial animals of this sort, of a form equivalent to a simple cell. When, therefore, the theory of the animal descent of man is condemned as a 'horrible, shocking, and immoral' doctrine, tho unalterable fact, which can be proved at any moment under the microscope, that the human egg is a simple cell, which is in no way different to those of other mammals, must equally be pronounced 'horrible, shocking, and immoral.”

“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.”

“There is no record in Scripture that an angel visited John’s cell to explain the meaning of his persecution. This great, godly man who was the designated forerunner to Jesus went through the same confusing experiences as we. It is comforting to know that John responded in a very human way. He sent a secret message to Jesus from his prison cell, asking “Are you the one who was to come, or should we expect someone else?” (Matthew 11:3). Have you ever felt like asking that question?”

“The most important impact on society and the world is the cell phone. Cell phones have actually been one of the primary drivers in productivity improvements.”

“The idea of prosthetics is a tool. Most people's cell phones are prosthetics. If you leave your cell phone at home, you feel impacted by not having it. It's an important part of your daily function and what you can do in a day.”

“If we ran Nigeria like this cell," he said, "we would have no problems in this country. Things are so organized. Our cell has a Chief called General Abacha and he has a second in command. Once you come in, you have to give them some money. If you don't, you're in trouble.”
