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?

As pointed out by Watson and Crick, the structure of DNA is central to its function, namely its duplication and its expression of the information contained in its nucleotide sequence. Thus ...

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 ...

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 ...

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 ...

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

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 ...

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 ...

The DNA molecule was composed of the traditional sugar backbones and nucleotide pairs, but rather than the well-known right-handed spiral of the double helix structure, famously discovered by Watson ...

RNA is more susceptible to hydrolysis (breaking down in the presence of water) compared to DNA, partly due to the absence ... same chemical formula but a different structure. It is often referred to ...
