"It takes time to bring your own ideas into a club and bring in a nucleus of players that you believe in".
The weak force between two protons in a nucleus is only 10−7 the strength of the electromagnetic force.
Systematic changes in level positions are seen as the number of neutrons in a nucleus is increased.
The number of neutrons in a nucleus affects the mass of the atom but not its chemical properties.
If the team achieves its goal, this will be the first time scientists have built the whole genome of a "eukaryotic" organism – one that stores its DNA in a nucleus.
If, however, there are too many or too few neutrons in a nucleus, that nucleus becomes unstable in other words, it is radioactive.
As the number of nucleons in a nucleus increases beyond about 40, the number of protons must be diluted with an excess of neutrons to maintain relative stability.
The number and the arrangement of neutrons and protons in a nucleus determine its spin, with higher spins corresponding roughly to faster rotation.
In general, the binding energy of a single proton or neutron in a nucleus is approximately a million times greater than the binding energy of a single electron in an atom.
This discovery seemed to complete the picture of atomic structure that had begun with Ernest Rutherford's work at the University of Manchester, England, in 1911, when it became apparent that almost all of the mass of an atom was concentrated in a nucleus.
But algae are on the other side of the great dividing line of life, that between creatures with a simple, single genome which is just a big loop of DNA sitting in the cell and those with genomes that are for the most part sequestered in a nucleus set aside for them, and cut up into multiple chromosomes.
