Molecular And Cell Biology Quotes & Sayings

Biology is far from understanding exactly how a single cell develops into a baby, but research suggests that human development can ultimately be explained in terms of biochemistry and molecular biology. Most scientists would make a similar statement about evolution. — Kenneth R. Miller

Suddenly I realized that a cell's life is controlled by the physical and energetic environment and not by its genes. Genes are simply molecular blueprints used in the construction of cells, tissues, and organs. The environment serves as a "contractor" who reads and engages those genetic blueprints and is ultimately responsible for the character of a cell's life. It is a single cell's "awareness" of the environment, not its genes, that sets into motion the mechanisms of life. — Bruce H. Lipton

When chemists artificially produce an amino acid or a sugar they almost always synthesize only a single product at a time, which they manage by carefully controlling the experimental conditions for the selected reaction, such as temperature and the concentrations of the various ingredients, to optimize the synthesis of their target compound. This is not an easy task and requires careful control of many different conditions inside customized flasks, condensers, separation columns, filtration devices and other elaborate chemical apparatus. Yet every living cell in your body is continually synthesizing thousands of distinct biochemicals within a reaction chamber filled with just a few millionths of a microliter of fluid.*7 How do all those diverse reactions proceed concurrently? And how is all this molecular action orchestrated within a microscopic cell? These questions are the focus of the new science of systems biology; but it is fair to say that the answers remain mysterious! — Johnjoe McFadden

If it's true there's a beginning to the universe, as modern cosmologists now agree, then this implies a cause that transcends the universe. If the laws of physics are fine-tuned to permit life, as contemporary physicists are discovering, then perhaps there's a designer who fine-tuned them. If there's information in the cell, as molecular biology shows, then this suggests intelligent design. To get life going in the first place would have required biological information; the implications point beyond the material realm to a prior intelligent cause. -Stephen C Meyer, PHD — Lee Strobel

A renaissance in cellular biology has recently revealed the molecular mechanisms by which thoughts and perceptions directly influence gene activity and cell behavior ... Energy psychology, through its ability to rapidly identify and reprogram limiting misconceptions, represents the most powerful and effective process to enhance physical and emotional well being. — Bruce H. Lipton

The big idea we start with is: "How is the genome interpreted, and how are stable decisions that affect gene expression inherited from one cell to the next?" This is one of the most competitive areas of molecular biology at the moment, and the students are reading papers that in some instances were published this past year. As a consequence, one of the most common answers I have to give to their questions is, "We just don't know." — Shirley M. Tilghman

Biology is run by intricate cellular mechanisms. Cellular mechanisms are run by Nature. Thus, the more we attempt to understand Nature, the more we get closer to our existential properties. — Abhijit Naskar

One of the major lessons in all of biochemistry, cell biology and molecular medicine is that when proteins operate at the sub cellular level, they behave in a certain way as if they're mechanical machinery. — James Rothman

To grasp the reality of life as it has been revealed by molecular biology, we must magnify a cell a thousand million times until it is twenty kilometers in diameter and resembles a giant airship large enough to cover a great city like London or New York. What we would then see would be an object of unparalleled complexity and adaptive design. On the surface of the cell we would see millions of openings, like the port holes of a vast space ship, opening and closing to allow a continual stream of materials to flow in and out. If we were to enter one of these openings we would find ourselves in a world of supreme technology and bewildering complexity. — Michael Denton

Evolution, cell biology, biochemistry, and developmental biology have made extraordinary progress in the last hundred years - much of it since I was weaned on schoolboy biology in the 1930s. Most striking of all is the sudden eruption of molecular biology starting in the 1950s. — John Tyler Bonner

The living cell is the most complex system of its size known to mankind. Its host of specialized molecules, many found nowhere else but within living material, are themselves already enormously complex. They execute a dance of exquisite fidelity, orchestrated with breathtaking precision. Vastly more elaborate than the most complicated ballet, the dance of life encompasses countless molecular performers in synergetic coordination. Yet this is a dance with no sign of a choreographer. No intelligent supervisor, no mystic force, no conscious controlling agency swings the molecules into place at the right time, chooses the appropriate players, closes the links, uncouples the partners, moves them on. The dance of life is spontaneous, self-sustaining, and self-creating. — Paul Davies

Look at any randomly selected piece of your world. Encoded deep in the biology of every cell in every blade of grass, in every insect's wing, in every bacterium cell, is the history of the third planet from the Sun in a Solar System making its way lethargically around a galaxy called the Milky Way. Its shape, form, function, colour, smell, taste, molecular structure, arrangement of atoms, sequence of bases, and possibilities for the future are all absolutely unique. There is nowhere else in the observable Universe where you will see precisely that little clump of emergent, living complexity. It is wonderful. — Brian Cox
