We are sometimes asked what the result would be if we put four +'s in one gene. To answer this my colleagues have recently put together not merely four but six +'s.
Unfortunately it makes the unambiguous determination of triplets by these methods much more difficult than would be the case if there were only one triplet for each amino acid.
This seems highly likely, especially as it has been shown that in several systems mutations affecting the same amino acid are extremely near together on the genetic map.
It seems likely that most if not all the genetic information in any organism is carried by nucleic acid - usually by DNA, although certain small viruses use RNA as their genetic material.
A final proof of our ideas can only be obtained by detailed studies on the alterations produced in the amino acid sequence of a protein by mutations of the type discussed here.
The important thing is that we now have the tools to sequence all kinds of animals and plants and microbes - as well as humans. It is not important that we didn't actually finish the human sequence yet.
I don't think of myself predicting things. I'm expressing possibilities. Things that could happen. To a large extent it's a question of how badly people want them to.
Gravitational and electromagnetic interactions are long-range interactions, meaning they act on objects no matter how far they are separated from each other.
I feel squeezed like a lemon - interviewers and people keep turning up unannounced at my office!
The curiosity of the human mind is essential if you want citizens who think rather than accept the first nonsense they come to.
We had to understand things like why the top quark was so heavy and the electron is so light. The Higgs is a big, important step.
Our research is so complex that the resources of a single region of the world are no longer enough - both intellectually and economically, it must be a global effort.
I turned my attention for a while to gamma ray astronomy and soon began the first in a continous series of experiments at the Savannah River site to study the properties of the neutrino.
Most of these experiments required the reduction of the cosmic ray muon flux in order to be successful, and the group necessarily became expert in the operation of deep underground laboratories.
Chemistry has been termed by the physicist as the messy part of physics, but that is no reason why the physicists should be permitted to make a mess of chemistry when they invade it.
In March of that year, I saw a man named Paul Barkley shot to death. It happened late at night in the parking lot of a café in Santa Rosa called Galileo’s.
In the hands of Science and indomitable energy, results the most gigantic and absorbing may be wrought out by skilful combinations of acknowledged data and the simplest means.
He had a broad face and a little round belly, that shook, when he laughed, like a bowlful of jelly.
I guess the two things I was most interested in were telescopes and steam engines. My father was an engineer on a threshing rig steam engine and I loved the machinery.
What you do is, you have your drawing board and a pencil in hand at the telescope. You look in and you make some markings on the paper and you look in again.
[My study of the universe] leaves little doubt that life has occurred on other planets. I doubt if the human race is the most intelligent form of life.
