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 ...

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?

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.

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.

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 ...
