Scientists at the University of California, Riverside, have discovered how adult stem cells retain their regenerative power.

(A) Nucleoside triphosphates serve as a substrate for DNA polymerase ... how the bottom strand in this diagram was synthesized. The asymmetric nature of the replication fork was recognized ...

During DNA replication, the unwinding of strands leaves a single strand vulnerable. How does the cell protect these strands from damage? How would you identify the protein that serves as a ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

Caption An illustration showing the approach for assembling biologically functional proteins into ordered 2D and 3D arrays through programmable octahedral-shaped DNA frameworks. These frameworks ...

A study links the loss of DNA methylation across the genome—as is common in cancer—to the disruption of the 3-D compartments that organize the genome and to the timing of DNA replication. Cell lines ...
