A high resolution structure of a dodecanucleotide confirms some accepted features of sequence-dependent DNA structure, highlights the possibility that other structural variations may be due to ...

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 ...

These bases intertwine in a spiral pattern to create the molecule's familiar double helix structure. The arrangement of these letters into sequences produces a code that instructs an organism on how ...

Most microscopes can only illuminate objects down to a certain size before tiny features blur together. This blurring is ...

The three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, ...
