In the test tube, I can make any DNA I want, recombining it from monkeys, worms, anywhere. So I can explore new rules of breeding with molecules.
Even if you couldn't see it beneath the surface, molecules were bonding, energy pushing up slowly, as something worked do hare, all alone to grow.
Chemistry is the science of atoms. Elaborating on Democritus' idea, chemists learn how atoms stick or don't stick together, thus forming molecules.
What I want to do is demonstrate that biology can learn how to make a vast array of molecules that people thought were outside the realm of biology.
We talk about quantum weirdness and things being in two places at once, but it all involves atoms and molecules, stuff we don't normally interact with.
Life wastes nothing. Over and over again every molecule that has ever been is gathered up by the hand of life to be reshaped into yet another form. p 259
This work made me more and more interested in biological matter, and I decided that I really wanted to work on the X-ray analysis of biological molecules.
According to materialistic science, any memory requires a material substrate, such as the neuronal network in the brain or the DNA molecules of the genes.
Whether we electrons, light quanta, benzol molecules, or stones, we shall always come up against these two characteristics, the corpuscular and the undular.
It now seems certain that the amino acid sequence of any protein is determined by the sequence of bases in some region of a particular nucleic acid molecule.
We are trying to find drugs, small molecules, that people could take to make them disease-resistant, more youthful and healthy. Eventually we will find them.
I know that the molecules in my body are traceable to phenomena in the cosmos. That makes me want to grab people on the street and say: ‘Have you HEARD THIS?
The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body.
Broadly speaking, the discovery of X-rays has increased the keenness of our vision ten thousand times, and we can now 'see' the individual atoms and molecules.
No matter how closely you examine the water, glucose, and electrolyte salts in the human brain, you can't find the point where these molecules became conscious.
The basic parts, the start-up molecules, can be supplied in abundance and don't have to be made by some elaborate process. That immediately makes things simpler.
The minute you have more than one voice, you have more possibilities opening up. You have all the molecules in all of those bodies and their make up interacting.
The actual atoms and molecules that make up my brain and body today are not the same ones that I was born with on September 8, 1954, a half-century ago this month.
Mainly I study the sense of touch and what the molecules are that transduce touch. And I use mutants in the nematode Caenorhabditis elegans to look at that problem.
Harry closed his eyes. He never wanted to open them again. His heart sent this message to his molecules: "For reasons obvious to all of us, this galaxy is dissolved!
Simply bringing awareness to the process of breathing initiates the release of peptide molecules from the hindbrain to regulate breathing while unifying all systems.
Darwinan evolution is limited to the biological aspect but before that happened the molecules themselves had to evolve to enable this further (biological) evolution.
People don't realize that molecules themselves are somewhat hypothetical, and that their interactions are more so, and that the biological reactions are even more so.
The physical relationship between CO2 molecules and the atmosphere and the trapping of heat is as well-established as gravity, for God's sakes. It's not some mystery.
Immunologists agreed that an individual vertebrate synthesizes many millions of structurally different forms of antibody molecules even before it encounters an antigen.
On the basis of Lorentz's theory, if we limit ourselves to a single spectral line, it suffices to assume that each atom (or molecule) contains a single moving electron.
Eventually I realised there must be a way by playing with the molecules; trying to turn the molecules on and off allows you to see adjacent things you couldn't see before.
The recipe for a human doesn't fill up a shopping list as you may suspect. Just twenty-two elements can describe almost all of the molecules that are, at this moment, you.
My own training is in the field of neuroendocrinology and I really became very fascinated many years ago with the molecules of emotion, molecules that we call neuropeptides.
Well, originally we found resveratrol just in a test tube, looking for molecules that would turn on this enzyme, this protein that seems to defend against diseases in aging.
I can see no practical application of molecular biology to human affairs... DNA is a tangled mass of linear molecules in which the informational content is quite inaccessible.
One day I discovered that one could get the barrier to internal rotation in ethane approximately right using this method. This was the beginning of my work on organic molecules.
Still I had a lurking question. Would it not be better if one could really 'see' whether molecules as complicated as the sterols, or strychnine were just as experiment suggested?
From a certain temperature on, the molecules 'condense' without attractive forces; that is, they accumulate at zero velocity. The theory is pretty, but is there some truth in it.
The structural or biogenetic relations of plant products as deduced from the recognizable architectural components of the molecules have been consistent guides in my investigations.
What attracted me to immunology was that the whole thing seemed to revolve around a very simple experiment: take two different antibody molecules and compare their primary sequences.
Nanotechnology is the idea that we can create devices and machines all the way down to the nanometer scale, which is a billionth of a meter, about half the width of a human DNA molecule.
Ultimately, biological phenomena involve molecules, and understanding them involves understanding the underlying chemistry. In my opinion, this is a particularly exciting area of chemistry.
The essential principles of the three-dimensional structure of organic molecules had been correctly formulated by the first Nobel laureate in Chemistry, Jacobus van't Hoff, as early as 1874.
Carbon-carbon bond formation reactions are important processes in chemistry because they provide key steps in building complex, bio-active molecules developed as medicines and agrochemicals.
Even a vortex is a vortex in something. You can't have a whirlpool without water; and you can't have a vortex without gas, or molecules or atoms or ions or electrons or something, not nothing.
When I began playing around at being a physical chemist, I enjoyed very much doing work on the structure of DNA molecules, something which I would never have dreamed of doing before I started.
Good live theater disturbs molecules. You create an energy source around yourself and it alternates between you and the audience. Anybody who sees live theater should come out a little rearranged.
Chiral receptor sites in the human body interact only with drug molecules having the proper absolute configuration, resulting in marked differences in the pharmacological activities of enantiomers.
The atoms may be compared to the letters of the alphabet, which can be put together into innumerable ways to form words. So the atoms are combined in equal variety to form what are called molecules.
We are made out of stardust. The iron in the hemoglobin molecules in the blood in your right hand came from a star that blew up 8 billion years ago. The iron in your left hand came from another star.
Traditional academic science describes human beings as highly developed animals and biological thinking machines. We appear to be Newtonian objects made of atoms, molecules, cells, tissues, and organs.
You may have heard the world is made up of atoms and molecules, but it's really made up of stories. When you sit with an individual that's been here, you can give quantitative data a qualitative overlay.
Consider that in this very moment, your body is changing as it reshuffles and exchanges its atoms and molecules with the rest of the universe - and you're doing it faster than you can change your clothes.
To get really high is to forget yourself. And to forget yourself is to see everything else. And to see everything else is to become an understanding molecule in evolution, a conscious tool of the universe.
