Viscoelastic solids have molecules in which the load-deformation relationship is time-dependent.
The department is a member of the public consortium racing to decode the genome, the DNA molecules in which the human hereditary information is inscribed.
They identified as the likely source of the problem a region on Chromosome 7, the seventh of the 23 pairs of giant molecules in which each human cell's DNA is packaged.
The decoding of the genome, the DNA molecules in which the human hereditary information is inscribed, is expected in time to transform medicine by revealing the genes that make the body vulnerable to disease.
This really was a technical breakthrough in materials science, since up till then it had only been possible to study isolated metal atoms and occasionally diatomic molecules, in which two atoms are bonded together.
Besides the 1,299 small gaps remaining, there is one major omission from the fly genome: the large DNA regions that form the central part of the fly's four chromosomes, the giant DNA molecules in which the genome is packaged.
The long, chainlike molecules, in which hydrogen atoms are connected to a carbon backbone, can be produced in linear or branched forms.
The ommins are large molecules, in which the chromogenic moiety is seemingly condensed with longer chains, such as peptides (amino acids linked together).
For example, fluorine gas consists of F2 molecules in which the fluorine atoms are bound together by sharing a pair of electrons, one contributed by each atom.
These free radicals are oxygen-rich molecules in which one of the oxygen atoms is particularly likely to react with other chemicals.
On cooling, the triply bonded P2 molecules condense to form tetrahedral P4 molecules, in which each atom is joined to three others by single bonds.
