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 ...

The tiny motor is positioned at the entrance of the virus shell, and feeds viral DNA into the shell as new viruses are assembled in a host cell. (Purdue News Service Graphic courtesy of Clark Gedney ...

The left-handed Z-DNA double helix is held together by traditional Watson-Crick base pairs, but unlike righthanded B-DNA, which has major and minor grooves between the twists of its sugar-phosphate ...

From synthetic biology and gene therapy to data storage and biofuel production, the demand for synthetic DNA is rising. (1) Chemicals remove the 5’-hydroxyl protecting group. The nucleosides are rich ...

Upper: The bacterium A. baylyi can incorporate DNA from its environment through natural competence. This allows horizontal gene transfer and the integration of cell-free DNA into the A.
