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 a linear molecule composed of four types of smaller chemical molecules called nucleotide bases ... together to form a double helix. The structure of DNA can also be described as a ladder.

First, he noted that the nucleotide composition of DNA varies ... that A bound to T and C bound to G within the molecular structure of DNA (Figure 2). Chargaff's realization that A = T and C ...

Shown here is the structure of naked DNA -- DNA without all of the proteins ... Each sugar-phosphate-base combination is called a nucleotide. A nucleotide is made up of 30 atoms, plus or minus ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single ... DNA mutations are changes in the nucleotide sequence of the ...

DNA achieves this feat of storing, coding and transferring biological information though its unique structure ... the process by which the sequence of nucleotide bases is determined for individual ...

Because the nucleotide bases that make up DNA bind ... was developed using a single DNA strand rather than a DNA origami structure. That earlier work was led by Kevin W. Plaxco (Ph.D. '94) of ...

Georgia State University researchers used simulations to study DNA repair mechanisms, focusing on the pre-incision complex in nucleotide excision repair.

Toribio Rodríguez de Mendoza National University researchers conducted a genomic analysis of fine aroma cocoa from northern ...

Each nucleotide consists of alternating sugar and phosphate sections with one of the four different bases attached to the sugar.

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...
