• DNA is the molecule that contains the genetic information that is passed from parents to offspring. (95 percent) • The lungs both take in oxygen molecules and eliminate carbon dioxide molecules.

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

Applied DNA has used its synthetic DNA tags, each just a billionth of the size of a grain of sugar, ... which are variations in the carbon, oxygen and hydrogen atoms in the cotton.

This article was originally published with the title “ Diversity Revealed: From Atoms to Traits ” in Scientific American Magazine Vol. 300 No. 1 (January 2009) doi:10.1038 ...

Commercial hard drives store a bit in at least 100,000 atoms---and even a DNA base pair is made of some thirty atoms. Both of these methods, like quantum computers themselves, are years from being ...

Journey Into Human DNA. By Rick Groleau; Posted 04.17.01; NOVA; Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human ...

DNA, which stands for deoxyribonucleic acid, resembles a long, spiraling ladder. It consists of just a few kinds of atoms: carbon, hydrogen, oxygen, nitrogen, and phosphorus.

EVERYTHING ON Earth is made of atoms, most of which are closely packed together in the form of minerals. Life has its uses for minerals—ask a coral reef—but its essence lies in atoms arranged ...

Neutron scientists have measured how fast sound travels along DNA to determine its ‘stiffness’. These findings help to explain how DNA folds, coils and denatures.

The structure of DNA was originally discovered using X-ray crystallography. This involves X-rays scattering off atoms in crystallised arrays of DNA to form a complex pattern of dots on ...

New research sheds light on how electrons interact with the innate vibrations within DNA molecules, known as phonons, which ...

Genetics DNA from across the ages can reveal migrations of Iron-Age people and genes that protected against ... Physicists spot elusive 'free-range' atoms ineracting in space for first time ...
