This means that one strand's sugar-phosphate chain runs in the 5 ... Crick were pursuing a definitive model for the stable structure of DNA inside cell nuclei. Watson and Crick ultimately used ...

Later it was found that the sugar in nucleic acid can ... just like the one before. This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations.

Its twisted, double-helix structure is one of the most ... it spells out the entire genetic code. Pentose sugars form part of the backbone of DNA and RNA strands, the sides of the ladder, to ...

Laying the Groundwork: Levene Investigates the Structure of DNA Meanwhile ... discovery of the sugar-phosphate backbone of the DNA molecule was still years away. The large number of molecular ...

Shown here is the structure of naked DNA -- DNA without all of the proteins ... The sides of the DNA ladder consist of a long string of sugar and phosphate molecules, to which the bases are ...

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

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 ...

(Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base pair, named after James Watson and Francis Crick, who first proposed the double helix structure of ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...
