Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three-dimensional shape. The first photographic evidence of this shape was ...

He isolated adenine from the pancreas of oxen and named it "adenine" derived from the Greek word "aden," meaning gland. Kossel was later awarded the Nobel Prize in Physiology or Medicine in 1910 for ...

DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine ... to form a double helix. The structure of DNA can also be described ...

Researchers swap nitrogen and boron into DNA to create analogues that are geometrically and electrostatically equivalent to ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures ... The DNA molecule is made up of four bases -- adenine (A), cytosine (C), guanine (G), and thymine ...

The basic units (monomers) of DNA are nucleotides. These nucleotides consist of a deoxyribose sugar, phosphate and base. The nucleotides are identical except for the base, which can be an adenine ...
