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 ...

We propose that PCNA slides by tracking the DNA backbone via a ‘cogwheel ... Coordinates and structure factors of the PCNA–dsDNA complex are deposited in the Protein Data Bank under accession ...
