Latest DNA replication Stories
UCLA biochemists have mapped the structure of a key protein–RNA complex that is required for the assembly of telomerase, an enzyme important in both cancer and aging.
The foundation of biological inheritance is DNA replication
Researchers at the RIKEN SPring-8 Center in Harima, Japan have clarified for the first time how chromatin in archaea, one of the three evolutionary branches of organisms in nature, binds to DNA.
Before any cell - healthy or cancerous - can divide, it has to replicate its DNA.
Inhibiting telomerase, an enzyme that rescues malignant cells from destruction by extending the protective caps on the ends of chromosomes, kills tumor cells but also triggers resistance pathways that allow cancer to survive and spread, scientists report in the Feb. 17 issue of Cell.
Genomic instability caused by an erosion of the protective caps on chromosomes, followed by activation of an enzyme that reinforces those caps, allows malignant cells to evade destruction and acquire more deadly characteristics, researchers report in an Online Now article at the journal Cell.
The cure for cancer comes down to this: video games.
It's been more than 50 years since James Watson and Francis Crick showed that DNA is a double helix of two strands that complement each other.
Scientists have found at least one instance when the smaller sibling gets to call the shots and cancer patients may one day benefit.
