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

This had helped her deduce that the phosphate part of the ... just like the one before. This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations.

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 ...

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 ...

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

(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 ...

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 ...
