DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

• 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 ...

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.

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 ...

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 ...

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 ...

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 ...
