Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that make up the human genome. ... A nucleotide is made up of 30 atoms, ...

• 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.

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 ...

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.

Your DNA consists of four bases, called cytosine, guanine, adenine, and thymine. A chemical unit called a methyl group, which contains one carbon and three hydrogen atoms, can be added to cytosine.
